Title
Specmurt Analysis of Multi-Pitch Music Signals with Adaptive Estimation of Common Harmonic Structure
Abstract
This paper describes a multi-pitch analysis method using specmurt analysis with iterative estimation of the quasi- optimal common harmonic structure function. Specmurt analysis (Sagayama et al., 2004) is based upon the idea that superimposed harmonic structure pattern can be ex- pressed as a convolution of two components, a funda- mental frequency distribution and a 'common harmonic structure' function if each underlying tone component has similar harmonic structure pattern. As proved in our pre- vious work (Sagayama et al., 2004) inappropriate com- mon structure function leads to inaccurate analysis results. The iterative algorithm proposed in this paper automati- cally chooses a proper structure, which results in finding concurrent multiple fundamental frequencies and reduces the dependency on heuristically chosen initial common harmonic structure. The experimental evaluation showed promising results.
