Abstract
A reference start point RPS and a reference end point RPE for detecting a beat position BP.sub.n are set as a BP.sub.n-1 +BT.+-.DR on the basis of a beat interval BT obtained by user's guide tapping for a predetermined time, a predetermined deviation value DR and the detected last beat position BP.sub.n-1. Thus, the crest value Lrp of an audio signal exceeding a predetermined threshold TH in the specified retrieval interval is obtained. Each beat position BP.sub.n is obtained on the basis of a reference point RS of the audio signal existing when the crest value is obtained. In reproduction of an audio signal by a DMTR, a MIDI clock is generated from the beat position and output to a MIDI sequencer, etc.
