[yupper,ylower] = envelope(x) returns the upper and lower envelopes of the input sequence, x, as the magnitude of its analytic signal. The analytic signal of x is found using the discrete Fourier transform as implemented in hilbert.The function initially removes the mean of x and adds it back after computing the envelopes. If x is a matrix, then envelope operates independently over …

how to separate an audio file based on different speakers

https://la.mathworks.com/matlabcentral/answers/1589774-how-to-separate-an-audio-file-based-on-different-speakers

this is ùy suggestion : assuming we have a wav file, I take the absolute of the signal and smooth it to get a kind of enveloppe , then I look for time instants when this enveloppe will cross a gievn threshold; this give me time values for start and stop times for each person.
