摘要：A method of binary allocation in an enhancement coding/decoding forimproving a hierarchical coding/decoding of digital audio signals, including a corecoding/decoding in a first frequency band and a band extension coding/decoding in asecond frequency band. For a predetermined number of bits to be allocated for theenhancement coding/decoding, a first number of bits is allocated to a coding/decodingfor correcting the core coding/decoding in the first frequency band and according to afirst mode of coding/decoding and a second number of bits is allocated to anenhancement coding/decoding for improving the extension coding/decoding in thesecond frequency band and according to a second mode of coding/decoding. Alsoprovided are an allocation module implementing the method and a coder and decoderincluding this module.
