'''Subband encodingcoding''' is anany form of [[audiotransform compressioncoding]] techniquethat wherebreaks thea soundsignal isinto splita intonumber of different [[frequency bandsband]]s and thenencodes each one independently. It can be used with [[audio compression]] so that 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.

SubbandFor example, subband encoding is used, for example, in [[MPEG-1]].
