I've got many audio files of the same scene, but recorded with different devices. I would like to automaticaly synchronize the sources.
I searched the web for a solution an I understood that I should compare two signals (with a cross-correlation), add a small delay to one signal, and re-compare the two signal until I have the less difference between them.
My problem is more with the implementation. Wich tool can do that ? I work with ffmpeg and I've seen that there is FFT tools included but with no documentation. How can I compare two signals ?
Thanks for your help.
