In 2001, the AES Technical Committee on Coding of Audio Signals (TC-CAS) produced the legendary educational CD ROM "Perceptual Audio Coders - What To Listen For". It contains a taxonomy of common types of codec artifacts, as well as tutorial information on the background of each one. Example audio signals with different degrees of impairment illustrate the nature of the artifacts and help in training test listener expertise. Since its initial release, several generations of CD ROMs were sold and found worldwide use for education of the public.
This workshop describes the TC's current efforts in producing a second-generation educational package that adds new artifact types as they can be typically experienced with advanced audio codec processing, such as bandwidth extension or parametric stereo. In addition, the format of the material was enhanced for seamless display and playback on PCs, tablets and mobile phones and includes interactive graphics elements. This makes it an attractive educational package that will be made available via AES publications.
We are working to provide the videos from Tuesday's and Wednesday's broadcasts as On Demand content. They will be available as soon as possible. All paid registrants will have access to this site/contents for some period of time post-convention.
