Under-Determined Reverberant Audio Source Separation Using a Full-Rank Spatial Covariance Model

TL;DR: In this article, the contribution of each source to all mixture channels in the time-frequency domain was modeled as a zero-mean Gaussian random variable whose covariance encodes the spatial characteristics of the source.

Under-determined reverberant audio source separation using a full-rank spatial covariance model

TL;DR: This paper addresses the modeling of reverberant recording environments in the context of under-determined convolutive blind source separation by model the contribution of each source to all mixture channels in the time-frequency domain as a zero-mean Gaussian random variable whose covariance encodes the spatial characteristics of the source.
Journal ArticleDOI

The signal separation evaluation campaign (2007-2010): Achievements and remaining challenges

TL;DR: The outcomes of three recent evaluation campaigns in the field of audio and biomedical source separation are presented and directions for future research and evaluation are proposed, based on the ideas raised during the related panel discussion at the Ninth International Conference on Latent Variable Analysis and Signal Separation.
Proceedings ArticleDOI

Nonnegative matrix factorization and spatial covariance model for under-determined reverberant audio source separation

TL;DR: This work addresses the problem of blind audio source separation in the under-determined and convolutive case by maximizing the likelihood of the mixture using an expectation-maximization (EM) algorithm.
Proceedings ArticleDOI

Audio Style Transfer

TL;DR: In this paper, a sound texture model is used to extract statistics characterizing the reference audio style, followed by an optimization-based audio texture synthesis to modify the target content, instead of random noise and the optimized loss is only about texture, not structure.
