From Klapuri, "Multipitch analysis of polyphonic music and
speech signals using an auditory model", from PolyPitch:
"The method consists of a computational model of the
human auditory periphery, followed by a periodicity analysis
mechanism where fundamental frequencies are iteratively
detected and canceled from the mixture signal."
Wow. That seems much different than all the other papers I read.
Wonder how well it works, especially if applied to guitar.
It sort of reminds me of how I once was part of Sony's rollout of
Surround Retrieval System technology.
It was TV surround speakers modeled based on human hearing,
to make one pair of these speakers simulate a truer surround.
Tim.
