EXHIBIT 99.1 Press Release Dated June 21, 2004 Digital Recorders, Inc. Announces Security-Related Equipment Order for Olympics DALLAS--(BUSINESS WIRE)--June 21, 2004--Digital Recorders, Inc. (DRI) (Nasdaq:TBUS), a market leader in transit, transportation and law enforcement digital communications and audio enhancement systems, announced today its Digital Audio Corporation (DAC) business unit has received an order for security-related equipment that will be used during the Games of the XXVIII Olympiad in Athens, Greece. "DAC is a well-established, respected supplier of investigative audio forensics and covert surveillance equipment for U.S. federal, state and local law enforcement agencies, as well as their counterparts in a number of countries. Out of respect for the customer and this order's security-related purpose, we are limiting our comments pertaining to specific order details. However, although this particular order is small, it does illustrate recognition of the utility of DAC's covert technologies in combating terrorism," David L. Turney, DRI's Chairman, Chief Executive Officer and President, said. Company Products Address Security Issues in Two Business Segments Mr. Turney also commented on the potential synergy from having been in its two business segments simultaneously for a number of years. "For many years DRI has been devoted to two business segments - -- the Transportation Communications Segment and the Law Enforcement and Surveillance Segment. While the Transportation Communications Segment has traditionally been primarily focused on passenger information systems, the vehicle locating and visual identification enhancement capabilities within that segment potentially also serve as security-risk mitigation in surface transit systems. The Law Enforcement and Surveillance Segment, while a small percentage of our annual revenue, has for many years served the needs of law enforcement agencies in the detection and apprehension of criminals. Therefore, given our cross-market knowledge base, we believe DRI is well positioned to address the growing concerns about security." About the Company's Law Enforcement and Surveillance Segment Founded in 1979 and acquired by DRI in 1995, the DAC business unit is a leading provider of forensic audio solutions for law enforcement, intelligence, military, and security organizations in a number of countries across the globe.
