Hi Bruno, So far, mirsimatrix does not work on large files. Changing the sampling rate of the audio input does not help, but changing the frame sampling does. MIRtoolbox 2.0 I am currently preparing (rebranded The MiningSuite, with a first version end of January) will be open source in the sense that the code will be documented and open to collaboration. So if anyone is interested in improving mirsimatrix, that would be highly welcome.
