Towards shifted NMF for improved monaural separation
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
The ability of Non-negative Matrix Factorisation (NMF) to decompose magnitude spectrogram into meaningful entities has found use in many audio applications. NMF can be used to factorise audio spectrogram of a music signal ...
Improved stereo instrumental track recovery using median nearest-neighbour inpainting
(Signals and Systems Conference (ISSC 2013), 24th IET Irish, 2013-06)
Several algorithms have been proposed for vocal removal which operate by finding the position of the vocals in the stereo field and removing the time-frequency bins associated with that position. However, in many cases, ...
