ABSTRACT:
A voice input to a microphone is converted by an A/D converter to a digital signal which is then delivered to a DSP, which extracts the notes of the input voice for determining same. The processing by the DSP includes bandpass filtering with a frequency corresponding to each note as the central frequency. A plurality of notes is processed on a time divisional basis to determine their respective notes. A new musical sound electronically corresponding to one or more notes extracted as the result of the note detection is then generated on a real time basis.
