Could I use this to distinguish human voices from machine beeps and/or ambient noise etc, by (after a few adaptations) calling it a number of times on the same set of samples with some representative set of frequencies? Or is there a better, less CPU-torturing way to do that?
Hi, I doubt, Mwanalyze will be versatile enough for that. I think, that would be another project. The only case, you could profit from Mwanalyze for your purpose, would be, if the machine noice/beep/tone will have _either_ a lot _or_ none portion of exectly one of the frequencies supported by Mwanalyze. Mwanalyze will e.g. tell you, that you have an amplitude of 300 (slin) of 500 Hz and a rest of another 10000 (slin). This would be an indicator for a synthetic 500 Hz tone. Whereas a 500 Hz amplitude of 0 would be an indicator for the absence of natural voice sources. Maybe under certain conditions this will be sufficient for your purpose. In general you will need a spectral analysis of (almost) the whole auditible spectral range.
