とする音声信号再生装置。 In an audio signal reproducing device that can speed up or slow down the readout speed of an audio signal recorded on a recording medium in a relationship that is not an integral multiple of the standard readout speed, the pitch of the reproduced sound changes as the readout speed changes. An audio signal reproducing device comprising: a pitch correction circuit that thins out or adds an audio signal to make the pitch the same as or almost the same as a standard pitch.
