Abstract
A frequency-domain sample interval corresponding to a time-domain pitch period L corresponding to a time-domain pitch period code of an audio signal in a given time period is obtained as a converted interval T, a frequency-domain pitch period T is chosen from among candidates including the converted interval Tand integer multiples U×Tof the converted interval T, and a frequency-domain pitch period code indicating how many times the frequency-domain pitch period T is greater than the converted interval Tis obtained. The frequency-domain pitch period code is output so that a decoding side can identify the frequency-domain pitch period T.
