Audio Engineering Society Releases Tutorial CD-ROM

The Audio Engineering Society's Technical Council (New York CIty) has launched a tutorial project on CD-ROM, Perceptual Audio Coders: What to Listen For. 1/16/2002 7:00 AM Eastern

The Audio Engineering Society's Technical Council (New York CIty) has launched a tutorial project on CD-ROM, Perceptual Audio Coders: What to Listen For. Developed by the Technical Committee on Coding of Audio Signals, and produced by Dr. Markus Erne, the unique CD-ROM is the first of its kind to be produced by the AES. It has been developed to familiarize audio engineers, broadcast engineers and audio students with the underlying principles of perceptual audio coding.

For more than 40 years, audio professionals have been trained in listening to conventional audio artifacts using analog equipment. Perceptual audio coding is a relatively new field and exhibits completely different types of artifacts. Perceptual Audio Coders: What to Listen For will be especially helpful to audio professionals, including engineers, designers and students, who are presented with audio material that has undergone audio compression, where the process of coding artifacts takes place.

The CD-ROM demonstrates the sonic side of audio technology, with examples of various types of audio coding artifacts. The artifacts are sorted according to type and severity as audio files, which enable listeners to enhance their ability to recognize these artifacts. Listeners are first presented with distortion grades that are obvious and then proceed to more subtle ones.

In addition to the CD-ROM's inclusion of 8 different chapters on audio coding artifacts, there are three tutorials on audio coding principles designed to familiarize the reader with the underlying technology.

Perceptual Audio Coders: What to Listen For is available for purchase at special introductory prices of $20.00 for non-members; $15.00 for members and $10.00 for student members. Additionally, libraries, research labs and institutes can obtain a volume discount.
