Abstract:
An audio signal decoding apparatus is provided that includes a receiver that receives an encoded information, a memory, and a processor that demultiplexes the encoded information, including encoding parameters that are used for decoding a low frequency spectrum and index information that identifies a most, correlated portion from a low frequency spectrum for one or more high frequency subbands. The processor also replicates a high frequency subband spectrum based on the index information using a synthesized low frequency spectrum, the synthesized low frequency spectrum being obtained by decoding the encoding parameters. The processor further estimates a frequency of a harmonic component in the synthesized low frequency spectrum, adjusts a frequency of a harmonic component in the high frequency subband spectrum using the estimated harmonic frequency, and generates an output signal using the synthesized low frequency spectrum and the high frequency subband spectrum.

Claim (Index 6):
The audio signal decoding apparatus according to  claim 1 , further comprising;\n a missing harmonic component identification section that identifies a harmonic component missing in the synthesized low frequency spectrum based on the estimated harmonic frequency; and a harmonic injection section that injects the missing harmonic component into the synthesized low frequency spectrum.
