Claim Text:
1. A method for allocating bits in an audio signal comprising: dividing a frequency band of an audio signal into a plurality of subbands; quantizing a subband normalization factor of each subband; grouping the plurality of subbands into a plurality of groups, wherein one group of the plurality of groups comprises one or more subbands; acquiring a group parameter of each group, wherein the group parameter represents an energy attribute of an audio signal of the corresponding group; allocating coding bits to at least one group according to the group parameter of each group, wherein a sum of a number of the coding bits allocated to each group of the at least one group corresponds to a number of coding bits of the audio signal, wherein one or more of the coding bits are allocated to a particular one of the at least one group; and allocating the one or more of the coding bits to at least one subband in the particular one group according to the subband normalization factor of each subband in the particular one group.
