Abstract
A karaoke type system allows a participant to sing on key with a prerecorded song. A microphone produces an input signal that corresponds to a singer's voice, and a pitch corrector samples the input vocal signal and determines its pitch. The pitch corrector reads a series of codes that are stored with the prerecorded song that indicates the pitch at which the input vocal signal is to be sung in order to be on key with the prerecorded song. The pitch corrector shifts the pitch of the input vocal signal to be on key.
