Intelligent Single-Channel Methods for Multi-Source Audio Analysis
This thesis investigates the potential of recent machine learning methods for the challenging task of single-channel, multi-source audio audio analysis, i.e., information extraction from single-channel audio where the sources of interest (e.g., speech) are mixed with multiple interfering sources. First, it is shown that source separation by recently proposed techniques for non-negative matrix f...
متن کاملAn Experimental Survey on Non-Negative Matrix Factorization for Single Channel Blind Source Separation
In applications such as speech and audio denoising, music transcription, music and audio based forensics, it is desirable to decompose a single-channel recording into its respective sources, commonly referred to as blind source separation (BSS). One of the techniques used in BSS is non-negative matrix factorization (NMF). In NMF both supervised and unsupervised mode of operations is used. Among...
متن کاملBlock Nonnegative Matrix Factorization for Single Channel Source Separation
Nonnegative Matrix Factorization (NMF) [1, 2] has been widely used in audio research, e.g. automatic music transcription [3], musical source separation [4], and speech enhancement [5]. The key strategy for applying NMF to audio-related tasks is to find a lower rank representation of the Short Time Fourier Transformed (STFT) input signal and use the basis vectors as dictionaries. For example, in...
متن کاملThèse De Doctorat
Given an audio signal that is a mixture of several sources, such as a music piece with several instruments, or a radio interview with several speakers, singlechannel audio source separation aims at recovering each of the source signals when the mixture signal is recorded with only one microphone. Since there are less sensors (one microphone) than sources (several sources), there is a priori an ...
