Method and apparatus for allocating bit in audio signal

摘要: A method and an apparatus for allocating bits in audio signal. The includes dividing a frequency band of signal into plurality subbands, quantizing subband normalization factor each subband; energy attribute the corresponding group; coding to at least one group, where sum allocated group is number signal; group. In case low or medium bit rate, embodiments present invention can, by means grouping, ensure relatively stable allocation previous subsequent frames reduce impact global on partial discontinuity.
