In this paper, audio perceptual compression systems are described, giving special attention to the former one: The MPEG 1, Layer III, in short, the MP3. Other compression technologies are described, especially the technologies evaluated in the present work: OGG Vorbis, WMA (Windows Media Audio) from Microsoft Corporation and AAC (Audio Coding Technologies).
