Organization, Consolidation and Presentation of Financial Statements [Abstract]
FINANCIAL INFORMATION	FINANCIAL INFORMATION The accompanying condensed consolidated financial statements include the accounts of Avid Technology, Inc. and its wholly owned subsidiaries (collectively, “we” or “our”). These financial statements are unaudited. However, in the opinion of management, the condensed consolidated financial statements reflect all normal and recurring adjustments necessary for their fair statement. Interim results are not necessarily indicative of results expected for any other interim period or a full year. We prepared the accompanying unaudited condensed consolidated financial statements in accordance with the instructions for Form 10-Q and, therefore, include all information and footnotes necessary for a complete presentation of operations, comprehensive income (loss), financial position and cash flows in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying condensed consolidated balance sheet as of December 31, 2017 was derived from the our audited consolidated financial statements and does not include all disclosures required by U.S. GAAP for annual financial statements. We filed audited consolidated financial statements as of and for the year ended December 31, 2017 in our Annual Report on Form 10-K for the year ended December 31, 2017 , which included information and footnotes necessary for such presentation. The financial statements contained in this Form 10-Q should be read in conjunction with the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017 . Our preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from our estimates. Subsequent Events On May 10, 2018 (the “Amendment No. 4 Effective Date”), we entered into an amendment (the “Fourth Amendment”) to the Financing Agreement. The Fourth Amendment extended the maturity of the Financing Agreement to May 2023 and increased the term and revolving facilities by an aggregate of $35.0 million . In addition, under the terms of the Fourth Amendment, the facility is subject to lower annual fees and interest rates, has a reduced principal amortization schedule and no longer includes a springing repayment feature related to the maturity of our Notes due in June 2020. We evaluated subsequent events through the date of issuance of these financial statements and, other than the event disclosed above, no other subsequent events required recognition or disclosure in these financial statements. Significant Accounting Policies - Revenue Recognition We enter into contracts with customers that include various combinations of products and services, which are typically capable of being distinct and are accounted for as separate performance obligations. The Company accounts for a contract when (i) it has approval and commitment from both parties, (ii) the rights of the parties have been identified, (iii) payment terms have been identified, (iv) the contract has commercial substance and (v) collectibility is probable. We recognize revenue upon transfer of control of promised products or services to customers, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts, in an amount that reflects the consideration we expect to receive in exchange for those products or services. See Note 9 for disaggregated revenue schedules and further discussion on revenue and deferred revenue performance obligations and the timing of revenue recognition. We often enter into contractual arrangements that have multiple performance obligations, one or more of which may be delivered subsequent to the delivery of other performance obligations. These arrangements may include a combination of products, support, training and professional services. We allocate the transaction price of the arrangement based on the relative estimated standalone selling price (“SSP”) of each distinct performance obligation. Our process for determining SSP for each performance obligation involves significant management judgment. In determining SSP, we maximize observable inputs and consider a number of data points, including: • the pricing of standalone sales (in the instances where available); • the pricing established by management when setting prices for deliverables that are intended to be sold on a standalone basis; • contractually stated prices for deliverables that are intended to be sold on a standalone basis; • other pricing factors, such as the geographical region in which the products are sold and expected discounts based on the customer size and type. Determining SSP for performance obligations which we never sell separately also requires significant judgment. In estimating the SSP, we consider the likely price that would have resulted from established pricing practices had the deliverable been offered separately and the prices a customer would likely be willing to pay. We only include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. We reduce transaction prices for estimated returns and other allowances that represent variable consideration under ASC 606, which we estimate based on historical return experience and other relevant factors, and record a corresponding refund liability as a component of accrued expenses and other current liabilities. Other forms of contingent revenue or variable consideration are infrequent. While not a common practice for us, in the event we grant the customer the option to acquire additional products or services in an arrangement, we consider if the option provides a material right to the customer that it would not receive without entering into the contract (e.g., an incremental discount compared to the range of discounts typically given for similar products or services). If a material right is deemed to exist, we account for the option as a distinct performance obligation and recognize revenue when those future products or services are transferred or when the option expires. We also record as revenue all amounts billed to customers for shipping and handling costs and record the actual shipping costs as a component of cost of revenues. Reimbursements received from customers for out-of-pocket expenses are recorded as revenues, with related costs recorded as cost of revenues. We present revenues net of any taxes collected from customers and remitted to government authorities. We apply the practical expedient to not adjust the transaction price for the effects of a significant financing component when we expect that the period between when we transfer a good or service to a customer and when the customer pays for that good or service will be one year or less. Payments under our contracts are typically due within in a short period from when our performance obligations are satisfied. We apply the practical expedient for the deferral of sales commissions and other contract acquisition costs, which are expensed as incurred, where the amortization period would be one year or less. Recently Adopted Accounting Pronouncements On January 1, 2018, we adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), using the modified retrospective method applied to contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. We recorded a net reduction to opening accumulated deficit of approximately $ 105 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606. The primary impact of ASC 606 that resulted in a significant decrease in deferred revenue is that vendor specific objective evidence of fair value is no longer required to recognize revenue for distinct software products upon delivery, which allows recognition upon delivery rather than on a ratable basis over a period of time. A summary of the changes to balance sheet line items that resulted from the adoption of ASC 606 as of January 1, 2018 is as follows (in thousands): As of January 1, 2018 As Previously Reported Impact of Adoption of Topic 606 (5) As Adjusted Assets: Accounts receivable, net (1) $ 40,134 $ 21,088 $ 61,222 Contract assets (2) — 6,579 6,579 Inventory (3) 38,421 (5,716 ) 32,705 Other long-term assets 10,811 865 11,676 Total assets $ 234,684 $ 22,816 $ 257,500 Liabilities: Accrued expenses and other current liabilities (1) $ 31,549 $ 11,139 $ 42,688 Deferred revenue (current portion) (4) 121,184 (37,794 ) 83,390 Long-term deferred revenue (4) 73,429 (55,079 ) 18,350 Total liabilities $ 503,254 $ (81,734 ) $ 421,520 Stockholders’ deficit: Accumulated deficit (1,284,703 ) 104,550 (1,180,153 ) Total stockholders’ deficit $ (268,570 ) $ 104,550 $ (164,020 ) (1) The increase in accounts receivable and accrued expenses and other current liabilities is due to the reclassification of allowances for sales returns, rebates and other adjustments to selling prices that are considered variable consideration under ASC 606 and are now presented as a liability on our balance sheet. Accounts receivable also increased due to advanced contractual support billings now being recorded on a gross basis in accounts receivable when it is due, rather than being net against corresponding unamortized deferred revenue. (2) For subscription contracts, we are now required under ASC 606 to record contract assets for annual and multi-year subscriptions that are billed monthly, resulting in an increase in contract assets at the date of adoption. In addition, some of our enterprise agreements have fixed payment schedules whereas the timing of the fulfillment of performance obligations under the contracts can vary, which can result in the fulfillment of performance obligations exceeding contract billings, which also results in contract assets. (3) The reduction is due to inventory and deferred costs that were directly attributable to deferred revenue transactions that were reduced or eliminated due to the adoption of ASC 606 (as described in footnote 4 below), necessitating the elimination of corresponding inventory and deferred costs associated with those deferred revenue transactions. (4) The reduction is primarily attributable to the elimination of the requirement to have vendor specific objective evidence of fair value for undelivered elements that existed under ASC 605, the prior applicable accounting guidance, for software products, which no longer precludes revenue recognition under ASC 606. (5) See Note 9 for a further description of the components of revenue and related performance obligations under ASC 606 that resulted in cumulative changes to balance sheet accounts as a result of the adoption of ASC 606. The adoption of Topic 606, as compared to legacy GAAP required for revenue recognition, did not have a significant impact on revenue or net loss for the three months ended March 31, 2018. The impact of ASC 606 to balance sheet line items as of March 31, 2018, after reflecting the opening balance sheet adjustments described in detail above, was not material. There was no tax impact associated with the adoption because our deferred tax assets related to deferred revenue have a full valuation allowance. In March 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”), No. 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin (“SAB”) No. 118 . The guidance amends SEC paragraphs in ASC 740, Income Taxes, to reflect and codify SAB No. 118, which provides guidance for companies that are not able to complete their accounting for the income tax effects of the Tax Cuts and Jobs Act in the period of enactment. The ASU became effective upon issuance. We had applied SAB 118 upon the original issuance in December, 2017 prior to the codification in ASC 740. See discussion below regarding the status of our accounting for the impacts of the Tax Cuts and Jobs Act (TCJA). On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) was signed into law. The TCJA changed many aspects of U.S. corporate income taxation and included reduction of the corporate income tax rate from 35% to 21% , implementation of a territorial tax system and imposition of a tax on deemed repatriated earnings of foreign subsidiaries. The TCJA was effective as of December 31, 2017 and at that time we made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. As of March 31, 2018, we have not completed our accounting for the tax effects of the TCJA nor have we recorded any adjustments during the quarter ended March 31, 2018. We will continue to assess our provision for income taxes as future guidance is issued, but do not currently anticipate significant revisions will be necessary. Any such revisions will be treated in accordance with the one year measurement period guidance outlined in Staff Accounting Bulletin No. 118. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions we have made, additional regulatory guidance that may be issued, and actions we may take as a result of the TCJA. The accounting is expected to be complete within the one year measurement period particularly after the 2017 U.S. corporate income tax return is filed in 2018. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flow (Topic 230) . The guidance reduces diversity in how certain cash receipts and cash payments are presented and classified in the Statements of Cash Flows. Certain of ASU No. 2016-15 requirements are as follows: (i) cash payments for debt prepayment or debt extinguishment costs should be classified as cash outflows for financing activities, (ii) contingent consideration payments made soon after a business combination should be classified as cash outflows for investing activities and cash payment made thereafter should be classified as cash outflows for financing up to the amount of the contingent consideration liability recognized at the acquisition date with any excess classified as operating activities, (iii) cash proceeds from the settlement of insurance claims should be classified on the basis of the nature of the loss, (iv) cash proceeds from the settlement of Corporate-Owned Life Insurance, or COLI, Policies should be classified as cash inflows from investing activities and cash payments for premiums on COLI policies may be classified as cash outflows for investing activities, operating activities, or a combination of investing and operating activities and (v) cash paid to a tax authority by an employer when withholding shares from an employee's award for tax-withholding purposes should be classified as cash outflows for financing activities. We adopted the guidance on January 1, 2018. The adoption of ASU 2016-15 had no material impact on our consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) . The guidance requires companies to recognize the income tax effects of intercompany sales and transfers of assets, other than inventory, in the income statement as income tax expense (or benefit) in the period in which the transfer occurs. We adopted the guidance on January 1, 2018. The adoption of ASU 2016-16 had no impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The guidance requires companies to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, companies will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. When cash, cash equivalents, restricted cash and restricted cash equivalents are presented in more than one line item on the balance sheet, a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet is required. We adopted the guidance on January 1, 2018. The adoption of ASU 2016-18 had no material impact on our consolidated financial statements. Restricted cash amounts, presented within the statements of financial position and cash flows, are cash collateralized letters of credit that are used as security deposits in connection with our facility leases and operations. Recent Accounting Pronouncements to be Adopted On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The guidance requires an entity to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The new guidance becomes effective for us on January 1, 2019, and early adoption is permitted upon issuance. We are currently evaluating the impact of this guidance on our consolidated financial statements and have compiled an initial inventory of our leases. These leases are primarily related to office space in the United States and foreign locations and are currently classified as operating leases under generally accepted accounting principles.

Earnings Per Share [Abstract]
NET INCOME PER SHARE	NET INCOME PER SHARE Net income per common share is presented for both basic income per share (“Basic EPS”) and diluted income per share (“Diluted EPS”). Basic EPS is based on the weighted-average number of common shares outstanding during the period. Diluted EPS is based on the weighted-average number of common shares and common share equivalents outstanding during the period. The potential common shares that were considered anti-dilutive securities were excluded from the diluted earnings per share calculations for the relevant periods either because the sum of the exercise price per share and the unrecognized compensation cost per share was greater than the average market price of our common stock for the relevant period, or because they were considered contingently issuable. The contingently issuable potential common shares result from certain stock options and restricted stock units granted to our employees that vest based on performance conditions, market conditions, or a combination of performance and market conditions. The following table sets forth (in thousands) potential common shares that were considered anti-dilutive securities at March 31, 2018 and 2017 . March 31, 2018 March 31, 2017 Options 2,262 2,654 Non-vested restricted stock units 3,172 2,613 Anti-dilutive potential common shares 5,434 5,267 On June 15, 2015, we issued $125.0 million aggregate principal amount of our 2.00% Convertible Senior Notes due 2020, or the Notes. The Notes are convertible into cash, shares of our common stock or a combination of cash and shares of common stock, at our election, based on an initial conversion rate, subject to adjustment. In connection with the offering of the Notes, we entered into a capped call transaction with a third party. We use the treasury stock method in computing the dilutive impact of the Notes. The Notes are convertible into shares of our common stock but our stock price was less than the conversion price as of March 31, 2018 and 2017 , and, therefore, the Notes are excluded from Diluted EPS. The Capped Call is not reflected in diluted net income per share as it will always be anti-dilutive.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Assets Measured at Fair Value on a Recurring Basis We measure deferred compensation investments on a recurring basis. As of March 31, 2018 and December 31, 2017 , our deferred compensation investments were classified as either Level 1 or Level 2 in the fair value hierarchy. Assets valued using quoted market prices in active markets and classified as Level 1 are money market and mutual funds. Assets valued based on other observable inputs and classified as Level 2 are insurance contracts. The following tables summarize our deferred compensation investments measured at fair value on a recurring basis (in thousands): Fair Value Measurements at Reporting Date Using March 31, Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Financial assets: Deferred compensation assets $ 1,647 $ 389 $ 1,258 $ — Fair Value Measurements at Reporting Date Using December 31, 2017 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Financial assets: Deferred compensation assets $ 1,743 $ 484 $ 1,259 $ — Financial Instruments Not Recorded at Fair Value The carrying amounts of our other financial assets and liabilities including cash, accounts receivable, accounts payable and accrued liabilities approximate their respective fair values because of the relatively short period of time between their origination and their expected realization or settlement. As of March 31, 2018 , the net carrying amount of the Notes was $105.8 million , and the fair value of the Notes was approximately $100.9 million based on open market trading activity, which constitutes a Level 1 input in the fair value hierarchy.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES Commitments We entered into a long-term agreement to purchase a variety of information technology solutions from a third party in the second quarter of 2017, which included an unconditional commitment to purchase a minimum of $12.8 million of products and services over the initial three -year term of the agreement. We have purchased $2.3 million pursuant to this agreement as of March 31, 2018 to develop Azure certified solutions. We have letters of credit that are used as security deposits in connection with our leased Burlington, Massachusetts office space. In the event of default on the underlying leases, the landlords would, at March 31, 2018 , be eligible to draw against the letters of credit to a maximum of $1.3 million in the aggregate. The letters of credit are subject to aggregate reductions provided we are not in default under the underlying leases and meet certain financial performance conditions. In no case will the letters of credit amounts be reduced to below $1.2 million in the aggregate throughout the lease periods, all of which extend to May 2020. We also have letters of credit in connection with security deposits for other facility leases totaling $1.1 million in the aggregate, as well as letters of credit totaling $1.4 million that otherwise support our ongoing operations. These letters of credit have various terms and expire during 2018 and beyond, while some of the letters of credit may automatically renew based on the terms of the underlying agreements. We issued a letter of credit totaling $8.5 million to one of our sole-source suppliers in the first quarter of 2018. The supplier is eligible to draw on the letter of credit in the event that we are insolvent or unable to pay on our purchase orders for certain key hardware components of our product. The letter of credit is valid for one year from issuance date, February 6th, 2018, and may automatically renew based on the terms of the underlying agreement. Contingencies Our industry is characterized by the existence of a large number of patents and frequent claims and litigation regarding patent and other intellectual property rights. In addition to the legal proceedings described below, we are involved in legal proceedings from time to time arising from the normal course of business activities, including claims of alleged infringement of intellectual property rights and contractual, commercial, employee relations, product or service performance, or other matters. We do not believe these matters will have a material adverse effect on our financial position or results of operations. However, the outcome of legal proceedings and claims brought against us is subject to significant uncertainty. Therefore, our financial position or results of operations may be negatively affected by the unfavorable resolution of one or more of these proceedings for the period in which a matter is resolved. Our results could be materially adversely affected if we are accused of, or found to be, infringing third parties’ intellectual property rights. In November 2016, a purported securities class action lawsuit was filed in the U.S. District Court for the District of Massachusetts (Mohanty v. Avid Technology, Inc. et al., No. 16-cv-12336) against us and certain of our executive officers seeking unspecified damages and other relief on behalf of a purported class of purchasers of our common stock between August 4, 2016 and November 9, 2016, inclusive. The complaint purported to state a claim for violation of federal securities laws as a result of alleged violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder. The complaint’s allegations relate generally to our disclosure surrounding the level of implementation of our Avid NEXIS solution product offerings. On February 7, 2017, the Court appointed a lead plaintiff and counsel in the matter. On June 14, 2017, we moved to dismiss the action. On July 31, 2017, the lead plaintiff filed an opposition to our motion to dismiss, and on August 21, 2017, we filed our reply brief. On October 13, 2017, after a mediation, the parties reached an agreement in principle to settle this litigation. We expect the majority of the settlement to be funded by our insurers. Finalization of the settlement is subject to a number of conditions, including execution of definitive documentation and approval by the court. Following the termination of our former Chairman and Chief Executive Officer on February 25, 2018, we received a notice alleging that we breached the former employee’s employment agreement. While we intend to defend any claim vigorously, when and if a claim is actually filed, we are currently unable to estimate an amount or range of any reasonably possible losses that could occur as a result of this matter. We consider all claims on a quarterly basis and based on known facts assess whether potential losses are considered reasonably possible, probable and estimable. Based upon this assessment, we then evaluate disclosure requirements and whether to accrue for such claims in our condensed consolidated financial statements. We record a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. At March 31, 2018 and as of the date of filing of these condensed consolidated financial statements, we believe that, other than as set forth in this note, no provision for liability nor disclosure is required related to any claims because: (a) there is no reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim, (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial. Additionally, we provide indemnification to certain customers for losses incurred in connection with intellectual property infringement claims brought by third parties with respect to our products. These indemnification provisions generally offer perpetual coverage for infringement claims based upon the products covered by the agreement and the maximum potential amount of future payments we could be required to make under these indemnification provisions is theoretically unlimited. To date, we have not incurred material costs related to these indemnification provisions; accordingly, we believe the estimated fair value of these indemnification provisions is immaterial. Further, certain of our arrangements with customers include clauses whereby we may be subject to penalties for failure to meet certain performance obligations; however, we have not recorded any related material penalties to date. We provide warranties on externally sourced and internally developed hardware. For internally developed hardware, and in cases where the warranty granted to customers for externally sourced hardware is greater than that provided by the manufacturer, we record an accrual for the related liability based on historical trends and actual material and labor costs. The following table sets forth the activity in the product warranty accrual account for the three months ended March 31, 2018 and 2017 (in thousands): Three Months Ended March 31, 2018 2017 Accrual balance at beginning of year $ 2,545 $ 2,518 Accruals for product warranties 505 806 Costs of warranty claims (568 ) (634 ) Accrual balance at end of period $ 2,482 $ 2,690 The warranty accrual is included in the caption “accrued expenses and other current liabilities” in our condensed consolidated balance sheet.

Restructuring and Related Activities [Abstract]
RESTRUCTURING COSTS AND ACCRUALS	RESTRUCTURING COSTS AND ACCRUALS In February 2016, we committed to a restructuring plan that encompassed a series of measures intended to allow us to more efficiently operate in a leaner, more directed cost structure. These included reductions in our workforce, consolidation of facilities, transfers of certain business processes to lower cost regions, and reductions in other third-party services costs. The cost efficiency program was substantially complete as of December 31, 2017. In April 2018, we determined that the estimated sublease rentals for the partially abandoned facilities in Burlington, Massachusetts, can no longer be reasonably obtained because of our plan to recapture the darkened space and the unlikelihood of sublet given the leases will terminate in two years. As a result, we recorded $2.7 million of facility restructuring costs adjustments during the quarter ended March 31, 2018 . In addition, we recorded $0.2 million of severance costs adjustments during the quarter ended March 31, 2018 . During the quarter ended March 31, 2017 , we recorded restructuring charges of $1.3 million , related to severance costs for the elimination of an additional 44 positions worldwide, and recoveries of $0.5 million related to severance estimate adjustments, and $0.2 million for the partial closure of Pinewood Studios facilities in Iver Heath, United Kingdom. Restructuring Summary The following table sets forth restructuring expenses recognized for the three months ended March 31, 2018 and 2017 (in thousands): Three Months Ended March 31, 2018 2017 Employee $ 168 $ 676 Facility 2,690 259 Total facility and employee charges 2,858 935 Other 49 48 Total restructuring charges, net $ 2,907 $ 983 The following table sets forth the activity in the restructuring accruals for the three months ended March 31, 2018 (in thousands): Employee Facility Total Accrual balance as of December 31, 2017 $ 1,998 $ 2,479 $ 4,477 Restructuring charges and revisions 168 2,690 2,858 Accretion — 55 55 Cash payments (1,184 ) (1,043 ) (2,227 ) Foreign exchange impact on ending balance 14 — 14 Accrual balance as of March 31, 2018 $ 996 $ 4,181 $ 5,177 Less: current portion 996 2,189 3,185 Long-term accrual balance as of March 31, 2018 $ — $ 1,992 $ 1,992 The employee restructuring accrual at March 31, 2018 represents severance costs to former employees that will be paid out within 12 months, and is, therefore, included in the caption “accrued expenses and other current liabilities” in our condensed consolidated balance sheets as of March 31, 2018 . The facility restructuring accrual at March 31, 2018 represents contractual lease payments, net of actual or estimated sublease income, on space vacated as part of our restructuring actions. The leases, and payments against the amounts accrued, extend through 2026 unless we are able to negotiate earlier terminations. Of the total facility restructuring balance, $2.2 million is included in the caption “accrued expenses and other current liabilities” and $2.0 million is included in the caption “other long-term liabilities” in our condensed consolidated balance sheet as of March 31, 2018 .

REVENUE (Notes)

Segment Reporting Information [Line Items]
PRODUCT AND GEOGRAPHIC INFORMATION	Revenue Components and Performance Obligations Video Products and Solutions We offer a wide range of video products and solutions from sales of storage and workflow solutions, our media management solutions and our video creative tools, which include our Media Composer, NEXIS, Airspeed, Maestro and Media Central product lines that consist of software licenses or integrated hardware and software solutions. We sell these products to customers under a contract or signed quote and payment terms are generally 30 to 60 days from delivery. Each individual product sold to a customer represents a distinct performance obligation for us and revenue is recognized at the point in time when control of the product transfers, which is typically when the product is shipped to the customer or, in the case of certain software licenses, when the software license term commences and is accessible by the customer. Audio Products and Solutions We offer a wide range of audio products and solutions from sales of digital audio software and workstation solutions and our control surfaces, consoles and live-sound systems, which include our Pro Tools, Pro Tools HD, Pro Tools | S6, VENUE | S6L and Sibelius product lines that consist of software licenses or integrated hardware and software solutions. We sell these products to customers under a contract or signed quote and payment terms are generally 30 to 60 days from delivery. Each individual product sold to a customer represents a distinct performance obligation for us and revenue is recognized at the point in time when control of the product transfers, which is typically when the product is shipped to the customer or, in the case of certain software licenses, when the software license term commences and is accessible by the customer. Subscription Services We offer subscription versions of many of our software products with monthly, annual and multi-year terms. While we are beginning to offer subscription versions for most of our product portfolio in connection with our cloud strategy, current subscription sales primarily consist of our Media Composer, Pro Tools and Sibelius offerings. We sell these products to customers under standard terms and conditions and payment is due upfront, except for webstore transactions which are billed monthly. Contract assets for annual and multi-year subscriptions billed monthly are recorded on our balance sheet upon customer commitment. Subscription services have several performance obligations, including a right to use the software and stand-ready performance obligations to (i) provide unspecified bug fixes and software enhancements, or Software Updates, and (ii) call support when and if needed. The estimated SSP of the right to use the licensed software is recognized at a point in time once control has been transferred and the customer has the ability to access the software. Stand-ready performance obligations related to Software Updates and call support are satisfied over time and revenue is recognized ratably over the term of the subscription. Support Services We offer support contracts, which are typically annual, for our video and audio products. Support contracts for individual products are sold bundled with initial product offerings or as renewals once initial contracts have lapsed. Support contracts are also sold on an enterprise basis where a customer purchases support for all Avid products owned. Support contracts are provided under our standard terms and conditions and payment is due in advance of the support being provided. Support contracts include stand-ready performance obligations to provide (i) Software Updates, (ii) call support and (iii) hardware maintenance. Support contract performance obligations are satisfied over time and revenue is recognized ratably over the term of the support contract. Historically, for many of our products, we had an ongoing practice of making when-and-if-available Software Updates available to customers free of charge for a period of time after initial sales to customers. The expectation created by this practice of providing free Software Updates represents an implied obligation of a form of post-contract customer support (“Implied PCS”) which represents a performance obligation. While we have ceased providing Implied PCS on new product offerings, we continue to provide Implied PCS for older products that were predominately sold in prior years. Revenue attributable to Implied PCS performance obligations is recognized over time on a ratable basis over the period that Implied PCS is expected to be provided, which is typically six years. Professional Services, Training and Other We sell a variety of professional services, training and other services that complement product and support offerings. Professional services consist primarily of standard configuration, commissioning (i.e., setting up equipment purchased) and on-air support (i.e., monitoring a customer’s production environment available during initial system go-live, live sporting events, etc.) and providing customization services for some of our products. We also offer training and certification programs for many of our products and workflows. Other revenues include shipping and handling charges and reimbursable travel expenses. We sell professional services, training and other services under contracts, signed quote and, for larger projects, statements of work that outline the customer’s specifications and requirements. Services are primarily sold on a time and materials basis, however, fixed fee arrangements are also executed from time to time. Payments are generally billed upon completion of the service or, for larger projects, on an installment basis as services are rendered. While the nature of service deliverables can vary significantly, each service deliverable generally represents a distinct performance obligation and revenue is recognized over time, typically in proportion of the total hours incurred as a percentage of total estimated hours required to complete the project. Enterprise Agreements From time to time, we enter into enterprise wide agreements whereby the customer agrees to purchase specified products and services from us over an extended period of time, often for a single fixed contractual price. For such agreements, management identifies each performance obligation in the contract and allocates the total contract price to each performance obligation based on relative estimated SSP. Once the transaction price is allocated to individual performance obligations, the components are recognized in the respective categories of revenue above consistent with the timing of the recognition of performance obligations described therein. Disaggregated Revenue and Geography Information Through the evaluation of the discrete financial information that is regularly reviewed by the chief operating decision makers (our chief executive officer and chief financial officer), we have determined that the Company has one reportable segment.

The Notes pay interest semi-annually on June 15 and December 15 of each year at an annual rate of 2.00% and mature on June 15, 2020, unless earlier converted or repurchased in accordance with their terms prior to such date. Total interest expense for the three months ended March 31, 2018 and 2017 was $2.2 million and $2.1 million , respectively, reflecting the coupon and accretion of the discount. On December 15, 2017, we purchased 2,000 of our 125,000 outstanding Notes and settled $2.0 million of the Notes for $1.7 million in cash. We recorded $2.0 million extinguishment of debt, an immaterial amount of equity reacquisition, and an immaterial loss on the extinguishment of debt. On February 8, 2018, we purchased an additional 2,000 of our 123,000 outstanding Notes and settled another $2.0 million of the Notes for $1.7 million in cash. We recorded $2.0 million extinguishment of debt, an immaterial amount of equity reacquisition, and an immaterial loss on the extinguishment of debt. Credit Facility On February 26, 2016, we entered into the Financing Agreement with the Lenders. Pursuant to the Financing Agreement, the Lenders originally agreed to provide us with (a) a term loan in the aggregate principal amount of $100.0 million (the “Term Loan”), and (b) a revolving credit facility (the “Credit Facility”) of up to a maximum of $5.0 million in borrowings outstanding at any time. All outstanding loans under the Financing Agreement will become due and payable on the earlier of February 26, 2021 and the date that is 30 days prior to June 15, 2020 if the $121.0 million in outstanding principal of the Notes has not been repaid or refinanced by such time. We granted a security interest on substantially all of our assets to secure the obligations under the Credit Facility and the Term Loan. We borrowed the full amount of the Term Loan, or $100.0 million , as of the closing date of the Financing Agreement, and there were no amounts outstanding under the Credit Facility as of March 31, 2018 . We may prepay all or any portion of the Term Loan prior to its stated maturity, subject to the payment of certain fees based on the amount repaid. The Term Loan requires quarterly principal payments of $1.25 million, which commenced in June 2016. The Term Loan also requires us to use 50% of excess cash flow, as defined in the Financing Agreement, to repay outstanding principal of the loans under the Financing Agreement. The Financing Agreement contains customary representations and warranties, covenants, mandatory prepayments, and events of default under which our payment obligations may be accelerated. On March 14, 2017 (the “Amendment No. 1 Effective Date”), we entered into an amendment (the “First Amendment”) to the Financing Agreement. The First Amendment modified the covenant requiring us to maintain a Leverage Ratio (defined to mean the ratio of (a) total funded indebtedness to (b) consolidated EBITDA) such that following the Amendment No. 1 Effective Date, we are required to maintain a Leverage Ratio of no greater than 3.50:1.00 for the four quarters ended March 31, 2017, 4.20:1.00 for the four quarters ended June 30, 2017, 4.75:1.00 for the four quarters ended September 30, 2017, 4.80:1.00 for the four quarters ended December 31, 2017, 4.40:1.00 for each of the four quarters ending March 31, 2018 through March 31, 2019, respectively, and thereafter declining over time from 3.50:1.00 to 2.50:1.00. Following the Amendment No. 1 Effective Date, interest accrues on outstanding borrowings under the credit facility and the term loan (each as defined in the Financing Agreement) at a rate of either the LIBOR Rate (as defined in the Financing Agreement) plus 7.25% or a Reference Rate (as defined in the Financing Agreement) plus 6.25%, at our option. We recorded $2.3 million and $1.9 million of interest expense on the Term Loan for the three months ended March 31, 2018 and 2017 , respectively. As of March 31, 2018 , we were in compliance with the Financing Agreement covenants. On November 9, 2017 (the “Amendment No. 2 Effective Date”), we entered into an amendment (the “Second Amendment”) to the Financing Agreement. The Second Amendment extended an additional $15.0 million term loan to us, thereby increasing the aggregate principal amount of the term loan to $115.0 million . The Second Amendment also increased the amount of available revolving credit by $5.0 million to an aggregate amount of $10.0 million . The additional $15.0 million term loan must be repaid in quarterly principal payments of $0.2 million commencing in March 2018. The Second Amendment also granted us the ability to use up to $15.0 million to purchase Notes and modified the definition of consolidated EBITDA used in the Leverage Ratio calculation to adjust for expected changes in deferred revenue due to the adoption of ASC 606. On May 10, 2018 (the “Amendment No. 4 Effective Date”), we entered into an amendment (the “Fourth Amendment”) to the Financing Agreement. The Fourth Amendment extended the maturity of the Financing Agreement to May 2023 and increased the term and revolving facilities by an aggregate of $35.0 million . In addition, under the terms of the Fourth Amendment, the facility is subject to lower annual fees and interest rates, has a reduced principal amortization schedule and no longer includes a springing repayment feature related to the maturity of our Notes due in June 2020.

Financial Information [Abstract]
Revenue Recognition, Deferred Revenue [Policy Text Block]	Significant Accounting Policies - Revenue Recognition We enter into contracts with customers that include various combinations of products and services, which are typically capable of being distinct and are accounted for as separate performance obligations. The Company accounts for a contract when (i) it has approval and commitment from both parties, (ii) the rights of the parties have been identified, (iii) payment terms have been identified, (iv) the contract has commercial substance and (v) collectibility is probable. We recognize revenue upon transfer of control of promised products or services to customers, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts, in an amount that reflects the consideration we expect to receive in exchange for those products or services. See Note 9 for disaggregated revenue schedules and further discussion on revenue and deferred revenue performance obligations and the timing of revenue recognition. We often enter into contractual arrangements that have multiple performance obligations, one or more of which may be delivered subsequent to the delivery of other performance obligations. These arrangements may include a combination of products, support, training and professional services. We allocate the transaction price of the arrangement based on the relative estimated standalone selling price (“SSP”) of each distinct performance obligation. Our process for determining SSP for each performance obligation involves significant management judgment. In determining SSP, we maximize observable inputs and consider a number of data points, including: • the pricing of standalone sales (in the instances where available); • the pricing established by management when setting prices for deliverables that are intended to be sold on a standalone basis; • contractually stated prices for deliverables that are intended to be sold on a standalone basis; • other pricing factors, such as the geographical region in which the products are sold and expected discounts based on the customer size and type. Determining SSP for performance obligations which we never sell separately also requires significant judgment. In estimating the SSP, we consider the likely price that would have resulted from established pricing practices had the deliverable been offered separately and the prices a customer would likely be willing to pay. We only include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. We reduce transaction prices for estimated returns and other allowances that represent variable consideration under ASC 606, which we estimate based on historical return experience and other relevant factors, and record a corresponding refund liability as a component of accrued expenses and other current liabilities. Other forms of contingent revenue or variable consideration are infrequent. While not a common practice for us, in the event we grant the customer the option to acquire additional products or services in an arrangement, we consider if the option provides a material right to the customer that it would not receive without entering into the contract (e.g., an incremental discount compared to the range of discounts typically given for similar products or services). If a material right is deemed to exist, we account for the option as a distinct performance obligation and recognize revenue when those future products or services are transferred or when the option expires. We also record as revenue all amounts billed to customers for shipping and handling costs and record the actual shipping costs as a component of cost of revenues. Reimbursements received from customers for out-of-pocket expenses are recorded as revenues, with related costs recorded as cost of revenues. We present revenues net of any taxes collected from customers and remitted to government authorities. We apply the practical expedient to not adjust the transaction price for the effects of a significant financing component when we expect that the period between when we transfer a good or service to a customer and when the customer pays for that good or service will be one year or less. Payments under our contracts are typically due within in a short period from when our performance obligations are satisfied. We apply the practical expedient for the deferral of sales commissions and other contract acquisition costs, which are expensed as incurred, where the amortization period would be one year or less.

Income Tax, Policy [Policy Text Block]	On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) was signed into law. The TCJA changed many aspects of U.S. corporate income taxation and included reduction of the corporate income tax rate from 35% to 21% , implementation of a territorial tax system and imposition of a tax on deemed repatriated earnings of foreign subsidiaries. The TCJA was effective as of December 31, 2017 and at that time we made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. As of March 31, 2018, we have not completed our accounting for the tax effects of the TCJA nor have we recorded any adjustments during the quarter ended March 31, 2018. We will continue to assess our provision for income taxes as future guidance is issued, but do not currently anticipate significant revisions will be necessary. Any such revisions will be treated in accordance with the one year measurement period guidance outlined in Staff Accounting Bulletin No. 118. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions we have made, additional regulatory guidance that may be issued, and actions we may take as a result of the TCJA. The accounting is expected to be complete within the one year measurement period particularly after the 2017 U.S. corporate income tax return is filed in 2018.

New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements to be Adopted On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . The guidance requires an entity to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The new guidance becomes effective for us on January 1, 2019, and early adoption is permitted upon issuance. We are currently evaluating the impact of this guidance on our consolidated financial statements and have compiled an initial inventory of our leases. These leases are primarily related to office space in the United States and foreign locations and are currently classified as operating leases under generally accepted accounting principles.

Revenue, Initial Application Period Cumulative Effect Transition [Line Items]
Revenue from Contract with Customer [Text Block]	On January 1, 2018, we adopted Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), using the modified retrospective method applied to contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC 605. We recorded a net reduction to opening accumulated deficit of approximately $ 105 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606. The primary impact of ASC 606 that resulted in a significant decrease in deferred revenue is that vendor specific objective evidence of fair value is no longer required to recognize revenue for distinct software products upon delivery, which allows recognition upon delivery rather than on a ratable basis over a period of time. A summary of the changes to balance sheet line items that resulted from the adoption of ASC 606 as of January 1, 2018 is as follows (in thousands): As of January 1, 2018 As Previously Reported Impact of Adoption of Topic 606 (5) As Adjusted Assets: Accounts receivable, net (1) $ 40,134 $ 21,088 $ 61,222 Contract assets (2) — 6,579 6,579 Inventory (3) 38,421 (5,716 ) 32,705 Other long-term assets 10,811 865 11,676 Total assets $ 234,684 $ 22,816 $ 257,500 Liabilities: Accrued expenses and other current liabilities (1) $ 31,549 $ 11,139 $ 42,688 Deferred revenue (current portion) (4) 121,184 (37,794 ) 83,390 Long-term deferred revenue (4) 73,429 (55,079 ) 18,350 Total liabilities $ 503,254 $ (81,734 ) $ 421,520 Stockholders’ deficit: Accumulated deficit (1,284,703 ) 104,550 (1,180,153 ) Total stockholders’ deficit $ (268,570 ) $ 104,550 $ (164,020 ) (1) The increase in accounts receivable and accrued expenses and other current liabilities is due to the reclassification of allowances for sales returns, rebates and other adjustments to selling prices that are considered variable consideration under ASC 606 and are now presented as a liability on our balance sheet. Accounts receivable also increased due to advanced contractual support billings now being recorded on a gross basis in accounts receivable when it is due, rather than being net against corresponding unamortized deferred revenue. (2) For subscription contracts, we are now required under ASC 606 to record contract assets for annual and multi-year subscriptions that are billed monthly, resulting in an increase in contract assets at the date of adoption. In addition, some of our enterprise agreements have fixed payment schedules whereas the timing of the fulfillment of performance obligations under the contracts can vary, which can result in the fulfillment of performance obligations exceeding contract billings, which also results in contract assets. (3) The reduction is due to inventory and deferred costs that were directly attributable to deferred revenue transactions that were reduced or eliminated due to the adoption of ASC 606 (as described in footnote 4 below), necessitating the elimination of corresponding inventory and deferred costs associated with those deferred revenue transactions. (4) The reduction is primarily attributable to the elimination of the requirement to have vendor specific objective evidence of fair value for undelivered elements that existed under ASC 605, the prior applicable accounting guidance, for software products, which no longer precludes revenue recognition under ASC 606. (5) See Note 9 for a further description of the components of revenue and related performance obligations under ASC 606 that resulted in cumulative changes to balance sheet accounts as a result of the adoption of ASC 606.

Long-term Debt			$ 115,000
Debt Instrument, Collateral					We granted a security interest on substantially all of our assets to secure the obligations under the Credit Facility and the Term Loan.
Debt Instrument, Covenant Description				The Financing Agreement contains customary representations and warranties, covenants, mandatory prepayments, and events of default under which our payment obligations may be accelerated. On March 14, 2017 (the “Amendment No. 1 Effective Date”), we entered into an amendment (the “First Amendment”) to the Financing Agreement. The First Amendment modified the covenant requiring us to maintain a Leverage Ratio (defined to mean the ratio of (a) total funded indebtedness to (b) consolidated EBITDA) such that following the Amendment No. 1 Effective Date, we are required to maintain a Leverage Ratio of no greater than 3.50:1.00 for the four quarters ended March 31, 2017, 4.20:1.00 for the four quarters ended June 30, 2017, 4.75:1.00 for the four quarters ended September 30, 2017, 4.80:1.00 for the four quarters ended December 31, 2017, 4.40:1.00 for each of the four quarters ending March 31, 2018 through March 31, 2019, respectively, and thereafter declining over time from 3.50:1.00 to 2.50:1.00.
Line of Credit Facility, Interest Rate Description				Following the Amendment No. 1 Effective Date, interest accrues on outstanding borrowings under the credit facility and the term loan (each as defined in the Financing Agreement) at a rate of either the LIBOR Rate (as defined in the Financing Agreement) plus 7.25% or a Reference Rate (as defined in the Financing Agreement) plus 6.25%, at our option.
