21 Oct 2013 export_fig Exports figures nicely to a number of vector & bitmap formats. Author: Oliver Woodford

great, did it whereas matlab could not =) thanks

12 Apr 2013 Simple drums separation with NMF Illustrates the use of NMF for the separation of drums in polyphonic music Author: Antoine Liutkus

Hi, as mentioned in the description, this script makes use of the NMF and Signal classes that are available in Mathworks file exchange :
http://www.mathworks.com/matlabcentral/fileexchange/33451-stft-mdct-and-inverses-onset-and-pitch-detection
and
http://www.mathworks.com/matlabcentral/fileexchange/33452-practical-nmfntf-with-beta-divergence

cheers

01 Sep 2012 STFT, MDCT and inverses. Onset and pitch detection Short Time Fourier Transform, MDCT and their inverse. CQT. Onset and Pitch detection. Author: Antoine Liutkus

pitch detection function is back, along with MDCT and inverse

19 Jul 2012 STFT, MDCT and inverses. Onset and pitch detection Short Time Fourier Transform, MDCT and their inverse. CQT. Onset and Pitch detection. Author: Antoine Liutkus

The version currently uploaded does not have the pitch detection function due to a mistake I made. I'll update it shortly
