Abstract
A novel multipitch analysis based on specmurt with the sparseness of the common harmonic structure pattern is presented. The conventional specmurt analysis is based on the idea that a fundamental frequency distribution is expressed as a deconvolution of the observed spectrum by the common harmonic structure pattern. However, it is considered impossible to obtain the strictly correct model of the common harmonic structure since harmonic structures can slightly vary depending on the pitch. Therefore a new method to analyze the fundamental frequency distribution without modeling the common harmonic structure is proposed. In this method, many possible fundamental frequencies are prepared using observed spectrum peaks, and harmonic and nonharmonic structures corresponding to them are obtained by the deconvolution of observed spectrum. Then, based on the sparseness, L1 or L2 norms are applied to only the appropriate harmonic structures in order to obtain a correct harmonic structure. The experimental result shows the effectiveness of our proposed method.
