Subband encoding
Subband encoding is an audio compression technique where the sound is split into frequency bands and then parts of the signal which the ear cannot detect are removed, e.g. a quiet sound masked by a loud one. The remaining signal is encoded using variable bit-rates with more bits per sample being used in the mid frequency range..
Subband encoding is used, for example, in MPEG-1.
