Patent

CA 2151625

A sound effect adding system for use in a karaoke performance is provided which, when one person sings at a pitch differing from that required for a song, or with different timing from that of the song, automatically yields, in part, the same effect as if a chorus, duet or round is being performed by a plurality of persons. In one embodiment, the sound effect adding system accomplishes this by means of pitch conversion and/or delay of the audio input signal in response to pitch conversion and/or delay information deriving from stored performance information for a particular musical composition.
