Source/Filter Model for Unsupervised Main Melody Extraction From Polyphonic Audio Signals
TLDR
In this paper, we propose a new approach for the estimation and extraction of the main melody (and in particular the leading vocal part) from polyphonic audio signals. Expand

A Musically Motivated Mid-Level Representation for Pitch Estimation and Musical Audio Source Separation
TLDR
We propose a source/filter signal model which provides a mid-level representation of an audio mixture power spectrum as a decomposition onto a dictionary of pre-defined spectral shapes. Expand

Multichannel nonnegative tensor factorization with structured constraints for user-guided audio source separation
TLDR
This paper considers multichannel audio source separation from convolutive mixtures, possibly underdetermined (more sources than sensors). Expand

Main instrument separation from stereophonic audio signals using a source/filter model
TLDR
We propose a new approach to solo/accompaniment separation from stereophonic music recordings which extends a monophonic algorithm we recently proposed. Expand

Musical Audio Source Separation Based on User-Selected F0 Track
TLDR
A system for user-guided audio source separation is proposed, allowing the user to select the desired audio source, by means of the assumed fundamental frequency (F0) track of that source. Expand

Multimodal similarity between musical streams for cover version detection
TLDR
In this paper, we show that considering the mixture, an estimation of its main melody and its accompaniment as modalities allows us to propose new ways of defining the similarity between musical streams. Expand

Lower and upper bounds for approximation of the Kullback-Leibler divergence between Gaussian Mixture Models
TLDR
We propose lower and upper bounds for the Kullback-Leibler divergence, which lead to a new approximation and interesting insights into previously proposed approximations. Expand

An iterative approach to monaural musical mixture de-soloing
TLDR
We introduce a novel approach for monaural source separation with the specific aim to separate a polyphonic musical recording into two main sources: a main instrument (or melody) track and an accompaniment track. Expand
