lossless audio compression definition 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
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.
