MUSICAL INSTRUMENT ESTIMATION FOR POLYPHONY USING AUTOCORRELATION FUNCTIONS

Yoshiaki Tadokoro, Koji Tanishita

Abstract

This paper proposes a new musical instrument estimation of polyphony using autocorrelation functions. We notice that each musical instrument has each autocorrelation function. Polyphony can be separated into each monophony using comb filters ( H ( z) = 1 - z -N ). We can obtain the autocorrelation functions for the outputs of comb filters from the autocorrelation functions of the monophony. By the pattern patching between the autocorrelation functions for the output signals of the comb filters and ones calculated from monophony of each instrument, we can estimate the musical instruments for polyphony.
