Can anyone help, I'm trying to find a solution that would allow me the ability to look at a batch of .WAV files and detect ones which share a similar behaviour in the recording like the image attached.

  • $\begingroup$ Are you looking for large sections of silence or do you need to identify regions with similar, non-silent content? $\endgroup$ – Dave C Mar 29 '19 at 17:46
  • $\begingroup$ Also, is that silence literally zero-values or just a little bit of analog noise potentially from from the recording hardware? $\endgroup$ – Dave C Mar 29 '19 at 18:09
  • $\begingroup$ Have you looked at computing the energy of the signal and thresholding? The section of the signal with zero value should have zero energy. $\endgroup$ – Maxtron Mar 29 '19 at 21:55
