|Use of block floating representation and adaptive bit allocation for encoding high quality audio. Gives nicely detailed, general coverage of transform coding.
|Quantizing noise is lessened in a speech signal system by using adaptive bit allocation for subband channels, wherein subband information of digital words is represented in block-floating-point form, and normalized mantiss as may allow dropping a sign bit.
