Pitch estimation for musical sounds with percussion sound using resonator-type comb filters

Abstract

This paper proposes a new pitch estimation method using resonator-type comb filtersfor the musical sounds including a percussion sound. We can estimate the pitch by detecting the output having maximum amplitude in twelve resonator-type comb filters connected in parallel. We could obtain the pitch estimation with mean error 3.4 % for artificial musical sounds that are assumed to be the sounds for almost every kind musical instruments.

Extracting Characteristics of Speaker’s Voice Harmonic Spectrum - Design of Human Voice Feature Extraction Technique

“…Rest part of the signal is the spectral envelope characterizing vocal tract parameters of the given speaker. The spectral envelope is described by a set of the LPC coefficients (Campbell, 1997), (Tadokoro et al, 2007).…”
