audio, compression Any kind of audio compression in which

the original signal and the decoded signal are bitwise

identical. Lossless audio compression algorithms are usually

based on a data compression algorithm like PKzip or gzip

but specialized for PCM audio data. The signal is divided

into predictable tonal components and unpredictable noisy

components. Tonal components are stored as coefficients of a

predictor, the remaining signal is coded by a Rice,

Huffman, or arithmetic coder.
