ABSTRACT:
A music accompaniment machine processes a music accompaniment file to alter a stored beat of the music accompaniment file to match a beat established by a user. The machine identifies the beat of the user using a voice analyzer. The voice analyzer isolates the user's singing signal from excess background noise and appends segment position information to the singing signal, which is indicative of the beat established by the singer. A MIDI controller alters the musical beat of the music accompaniment file so that it matches the beat established by the user.
