considered to be the “bible” of audio design. He has over 100 published articles on
sound, acoustics and related topics.
Mr. Rayburn has taught audio systems and recording at Eastman School of Music and the
Institute of Audio Research. He was also a panelist at the 2000 Digital Audio Networks
seminar sponsored by Synergetic Audio Concepts and lectured at the 2001 and 2002

Mr. Rayburn has been an engineer in acoustics, audio systems, and telecommunications
for 44 years. He has notable experience in the design of legislative sound systems,
church sound and acoustics, and recording and broadcast studios. He has particular
expertise in the creation of highly customized "project files" for configurable digital
signal processing, digital audio networks, and has taught advanced training courses on
these topics. He is responsible for the design of advanced digital audio systems,
measurement of audio system performance, measurement and optimization of acoustic
environments, and the optimization of audio systems for their acoustic environments. He
also has expertise in the area of RFI interference elimination. With the recent
proliferation of GSM cell phones and Blackberries, this knowledge has proven
instrumental in assuring that his designs avoid the problems caused by these devices.
A holder of a license to use and teach Time Delay Spectrometry since 1978, Mr. Rayburn
has extensive experience in the use of TDS, TEF, Smaart and other acoustic measurement
systems, and the use of acoustic data in the design and re-design of acoustically critical
facilities. His design and development of audio and telecommunications products include

microphones to teleconferencing equipment, and tape duplicators to modems.
Mr. Rayburn has recorded the Chicago Symphony, the Philadelphia Orchestra, and Frank
Zappa for RCA Records; TV specials for HBO and Showtime; award winning albums for
