Digital audio compression

Compared to most digital data types, with the exception of digital video, the data rates associ-ated with uncompressed digital audio are substan-tial. Digital audio compression enables more effi-cient storage and transmission of audio data. The many forms of audio compression techniques offer a range of encoder and decoder complexity, compressed audio quality, and differing amounts of data com-pression. The -law transformation and ADPCM coder are simple approaches with low-complexity, low-compression, and medium audio quality algo-rithms. The MPEG/audio standard is a high-complexity, high-compression, and high audio qual-ity algorithm. These techniques apply to general au-dio signals and are not specifically tuned for speech signals
