This paper presents a probabilistic model that is used for decomposing music audio signals into the three elements of sound: pitches (fundamental frequencies: F0s), timbres (spectral envelopes), and volumes. Conventional composite autoregressive models cannot deal with log-frequency spectrograms that match the characteristics of human auditory perception. When pithed sounds are analyzed, it is inappropriate to focus on all the frequency bands not limited to harmonic partials for estimating the spectral envelopes. To solve these problems, we propose a nonparametric Bayesian model based on gamma processes called an infinite superimposed discrete all-pole model by incorporating the idea of discrete all-pole modeling into a composite autoregressive model. |
