                        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."

is a leading provider of forensic audio solutions for law enforcement,
