Technical Committee

Coding of Audio Signals

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.

Areas of Concentration

  1. Coding Research and Engineering
  2. Bit Rate Reduction Theory and Practice
  3. Human Perception Related to Coding

Current Areas Of Work

  • Parametric Multi-Channel/Multi-Object Audio Coding
  • Coding of 3D Audio Signals
  • Low Delay General Audio Coding
  • Combined Audio/Speech Coding
  • AI-Based Methods for Perceptual Audio Coding
  • Continuous work on the Web Edition of the TC’s popular educational tutorial package Perceptual Audio Coders – What to Listen for with an extended artifact inventory, enhanced presentation & playback on mobile devices and PCs. See Audio Coding Artifacts Tutorial section further down on this page.
