An ambient denoising method based on multi-channel non-negative matrix factorization for wheezing detection
Antonio J. Muñoz-Montoro, Pablo Revuelta-Sanz, Damian Martínez-Muñoz +2
In this paper, a parallel computing method is proposed to perform the background denoising and wheezing detection from a multi-channel recording captured during the auscultation pr…
Unsupervised detection and classification of heartbeats using the dissimilarity matrix in PCG signals
J. Torre-Cruz, D. Martinez-Munoz, N. Ruiz-Reyes +3
The proposed system consists of a two-stage cascade. The first stage performs a rough heartbeat detection while the second stage refines the previous one, improving the temporal lo…
Pre-trained Spatial Priors on Multichannel NMF for Music Source Separation
Pablo Cabanas-Molero, Antonio J. Munoz-Montoro, Julio Carabias-Orti +1
This paper presents a novel approach to sound source separation that leverages spatial information obtained during the recording setup. Our method trains a spatial mixing filter us…
Multichannel Singing Voice Separation by Deep Neural Network Informed DOA Constrained CNMF
Antonio J. Muñoz-Montoro, Julio J. Carabias-Orti, Archontis Politis +1
This work addresses the problem of multichannel source separation combining two powerful approaches, multichannel spectral factorization with recent monophonic deep-learning (DL) b…
A new definition of the distortion matrix for an audio-to-score alignment system
A. J. Muñoz-Montoro, P. Vera-Candeas, D. Suarez-Dou +1
In this paper we present a new definition of the distortion matrix for a score following framework based on DTW. The proposal consists of arranging the score information in a seque…
