    Hi, gang

    I've been listening to some hours-long meditative music videos on YouTube. What I'm trying to figure out is how much of the music was actually played and where the loop starts. Is there a way to do that in some more automated way? I was thinking that there may be a tool that can be given a sample of the first 5-10 seconds that can then search through the rest of the file and find a match.

    Any ideas?
    Thanks!

    Zooming the waveform and looking? Thats what I do many times when editing or sampling loop beat

    Of course, or what I've been doing, intently listening :) The problem is that these are performances that probably range in the five to twenty-minute range, they're not short loops.

    That shouldn't be a problem if you do what Legotron said.
    If there is silence after narration before the music, would it be possible to search for zero points?
    Other than that, visually in a wave editor.

    I reckon your best bet is combining your ear with what these guys have said. If you use a spectral analyser, like RX7 or 8, you might be able to see any obvious repetitions easier.
