Abstract

This paper proposes a framed-based extended MIDI-pitch detection algorithm based on variable sampling technology. Symbols P--, P-, P+ and P++ are used to present four different logarithmic frequencies around the MIDI pitch P (integer) within 100 cents interval and called as extended MIDI-pitch to enhance the expression resolution of MIDI pitch of a signal frame. Experiment shows that the algorithm has a good raw pitch accuracy rate and less computation complexity o(nlog2n).
