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.
A CD-ROM on audio coding artifacts with the title "Perceptual Audio Coders - What To Listen For" was prepared by the members of the AES Technical Committee on Coding of Audio Signals in 2001. This was 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 could also be played back on all standard audio CD players.
Inspired by the public's huge interest in the tutorial, a second and enhanced edition of this tutorial was prepared and finalized in 2021 ("The Web Edition"). To facilitate the use on many viewing devices, the content can be played back on both computers and mobile devices, such as tablets or mobile phones. The second-generation material features a number of enhancements including new material on advanced coding strategies (partially with interactive displays) and HTML5-based seamless audio playback.
Free tutorial access is available here. A promotional video is available here at YouTube.
