Abstract
A processing buffer unit stores an audio signal. A pitch calculation unit and a pitch cycle correction unit calculate a multiple of N as the number of samples in a pitch cycle of the audio signal, in which N is an integer equal to or more than 1. A processing control unit and a start-position movement amount correction unit sequentially determine, as a sample in a start position of a compression process in a time axis domain of the audio signal, a (multiple of N)-th sample from a start position immediately before the start position. An operation unit compresses samples in a predetermined number times the pitch cycle from the sample in the start position in a time axis domain, and sets the number of samples after the compression to be the multiple of N. The present technology, for example, may be applied to an audio signal processing apparatus.
