Meaning of SUBBAND ENCODING

 
Computing Dictionary
 
 Definition: 

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 in mpeg-1.
