I am trying to do MFCC extraction. As far as I get; the steps are
Read an "Audio"
Run "SpectralAnalysis" on output of "Audio"
Run "MelFilterBank" on output of "SpectralAnalysis"
Run "CepstralTransform" on output of "MelFilterBank"
If so; I cannot understand where to do looping, for example if I do:
it applies mfcc to each read audio patch (mentioned by Audio.SetSize)
and got one MFCC feature vector. But I cannot understand how
WindowSize or HopSize is applied in this fashion. Because since Audio
is read in non-overlapping windows with mReader.Do(), overlapped
windows are run only for current audio part
I think there must be another , more correct way to get overlapping
windows continuesly in whole audio, but cannot find it. Any ideas?
