lossless audio compression
<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 {Rice coding},
{Huffman coding} or {arithmetic coding}.
