AES Technical Committee: Coding of Audio Signals

Chair: James Johnston (Send E-mail)

Chair: Juergen Herre (Send E-mail)

Mission Statement:
This committee has as its scope the theory, study, research, practice, engineering, and other standing issues involving the coding (i.e. bit rate reduction) of audio signals, especially but not limited to methods that use knowledge of human perception in the coding process.
The goal of this committee is to further work, knowledge and interest in subjects within its scope, and to increase awareness of the methods, problems, and standards within the AES. Within its scope, the committee will provide an informal technical forum for discussion of scientific and engineering problems as well as non-technical matters, participate in convention programs at the invitation of Convention Chairs, and work with the editor of the JAES, allowing it to distribute accurate and timely information to the membership.

Audio Coding CD-ROM

A CD-ROM on audio coding artifacts was prepared by the members of the AES Technical Committee on Coding of Audio Signals. This is the first educational/tutorial CD-ROM presented by the AES Technical Council on a particular topic, combining background information with specific audio examples. To facilitate the use of high-quality home playback equipment for the reproduction of the audio excerpts, the disk can also be played back on all standard audio CD players. Available via AES publications!
