AUDIO CODING: BASICS AND STATE OF THE AR T
http://www.eeng.dcu.ie/~ee502/AudioCodingBasics.pdf
The basic task of a perceptual audio coding system is to compress the digital audio data in a way that - the compression is as efficient as possible, i.e. the compressed file is as small as possible and - the reconstructed (decoded) audio sounds exactly (or as close as possible) to the original audio before compression.
AUDIO CODING: BASIC PRINCIPLES AND RECENT …
http://www.mp3-tech.org/programmer/docs/Bosi.pdf
The basic principles behind the quantization, time to frequency mapping and psychoacoustic models stages of an audio coding system are analyzed. Emerging audio formats and new trends, such as parametric audio coding, perceptual noise substitution, PNS, spectral band replication, SBR, and sinusoidal modelling are examined.

©Yao Wang, 2004 EE3414: Audio Coding 18 Basic Steps in MPEG-1 Audio Coding 1. Use convolution filters to divide the audio signal into 32 frequency subbands --> sub-band filtering. 2. Determine amount of masking for each band based on its frequency (threshold-in-quiet), and the energy of its neighboring band in frequency and time

The Audio Programming Book is an invaluable resource for composers, sound designers, and programmers. The contributors have done an outstanding job of communicating not only the technology but also the artistry of programming audio applications. That art will surely flourish further, thanks to their efforts. Robert Rowe.

Audio Coding (cont.) In general, producing quantized sampled output for audio is called PCM (Pulse Code Modulation). The differences version is called DPCM (and a crude but efficient variant is called DM). The adaptive version is called ADPCM.
