Audio coders are part of our daily lives. Current applications include digital radio and television, digital sound on film, DVD, multimedia/Internet audio, portable devices, electronic music distribution, and 3rd generation mobile. This tutorial introduces basic principles behind perceptual audio coding systems and the design choices applied in different coding schemes, e.g., AC-3; MPEG Layers I, II, and III (MP3); MPEG AAC; MPEG-4; MPEG-Surround. Demonstrations will allow participants to hear different aspects of the audio coding process and potential artifacts as well as the quality of state-of-the-art implementations including parametric, bandwidth extension, and spatial audio coding at varying data rates.
