Differentiable Digital Signal Processing Mixture Model for Synthesis Parameter Extraction from Mixture of Harmonic Sounds

Masaya Kawamura, Tomohiko Nakamura, Daichi Kitamura +3

A differentiable digital signal processing (DDSP) autoencoder is a musical sound synthesizer that combines a deep neural network (DNN) and spectral modeling synthesis. It allows us…

Multichannel Audio Source Separation with Independent Deeply Learned Matrix Analysis Using Product of Source Models

Takuya Hasumi, Tomohiko Nakamura, Norihiro Takamune +4

Independent deeply learned matrix analysis (IDLMA) is one of the state-of-the-art multichannel audio source separation methods using the source power estimation based on deep neura…

Prior Distribution Design for Music Bleeding-Sound Reduction Based on Nonnegative Matrix Factorization

Yusaku Mizobuchi, Daichi Kitamura, Tomohiko Nakamura +3

When we place microphones close to a sound source near other sources in audio recording, the obtained audio signal includes undesired sound from the other sources, which is often c…

Joint-Diagonalizability-Constrained Multichannel Nonnegative Matrix Factorization Based on Multivariate Complex Sub-Gaussian Distribution

Keigo Kamo, Yuki Kubo, Norihiro Takamune +4

In this paper, we address a statistical model extension of multichannel nonnegative matrix factorization (MNMF) for blind source separation, and we propose a new parameter update a…

Regularized Fast Multichannel Nonnegative Matrix Factorization with ILRMA-based Prior Distribution of Joint-Diagonalization Process

Keigo Kamo, Yuki Kubo, Norihiro Takamune +4

In this paper, we address a convolutive blind source separation (BSS) problem and propose a new extended framework of FastMNMF by introducing prior information for joint diagonaliz…
