Abstract:
A coding apparatus includes a processor and a memory that stores instructions, which when executed causes the processor to perform operations, including encoding a first band of an input audio signal to be a first spectrum and dividing the first spectrum into a plurality of sub-bands. The operations also include searching a largest amplitude value of the divided first spectrum in each of the plurality of sub-bands, and normalizing the divided first spectrum in each of the plurality of sub-bands. The operations further include emphasizing a harmonic structure in the normalized first spectrum, and searching a best band that has a largest correlation value between each divided band of a second band spectrum and the emphasized first spectrum in which the harmonic structure is emphasized, and encoding the second band spectrum using lag information identifying the best band and transmitting the lag information to a decoder side.

Claim (Index 6):
The coding method according to  claim 5 ,\n wherein in searching the best band, only the emphasized first spectrum, which has a starting frequency position with non-zero amplitude in the normalized first spectrum is used.
