A Tutorial on MPEG/Audio Compression
Davis Pan, Motorola
This tutorial covers the theory behind MPEG/audio compression. While lossy, the algorithm often can provide “transparent,” perceptually lossless compression even with factors of 6-to-1 or more. It exploits the perceptual properties of the human auditory system. The article also covers the basics of psychoacoustic modeling and the methods the algorithm uses to compress audio data with the least perceptible degradation.
This tutorial covers the theory behind MPEG/audio compression. It is written for people with a modest background in digital signal processing and does not assume prior experience in audio compression or psychoacoustics. The goal is to give a broad, preliminary understanding ...
