Multichannel HR-NMF for modelling convolutive mixtures of non-stationary signals in the time-frequency domain
2013
2013 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics
In the literature, several probabilistic models involving latent components have been proposed for modelling time-frequency (TF) representations of audio signals (such as spectrograms), notably in the nonnegative matrix factorization (NMF) literature. Among them, the recent high resolution (HR)-NMF model is able to take both phases and local correlations in each frequency band into account, and its potential has been illustrated in applications such as source separation and audio inpainting.
