ABSTRACT:
A system and method to assist a singer or other user. An audio source is processed to extract the lead vocals from the audio signal. This vocal signal is fed to a pitch detection processor which estimates the pitch at each moment in time. A user singing into a microphone provides a user vocal signal that is also pitch detected. The pitch of the lead vocal signal and the user vocal signal are compared and any difference is provided to a pitch shifting module, which then can correct the pitch of the user vocal signal. The corrected user vocal signal may be combined with a background signal comprising a signal from the audio source without the lead vocal signal, and then provided to headphones or loudspeakers to the user and/or an audience. This system and method may be used for Karaoke performances.
