Any kind of program to match audio clips based on spectral analysis or something similar?
Basically, I have one audio file that is a string-out of several takes of voiceover dialogue (FILE “A”). I have another file that is the editing dialogue using the best takes from the string-out (FILE “B”). I now have to determine which takes from the string-out (A) were used in the editing dialogue clip (B)…. hard to tell the subtle differences by ear. Basically I’m looking for any kind of program that will scan the spectral of “B” and highlight the identical portions in “A”. Is this possible, or any other suggestions that may help? Thanks.

1) In the future, slate all your string outs; In this case it would be speaking in a cue of each file name proceeded with a beep
2) Use Plural Eyes, should work fine to sync the waveforms of each set of audio unless it’s really chopped up/pre-edited heavily. If the latter is the case then you’re out of luck.——————–

To clarify – the “stringout” is one take, a series of lines several times in the same take. That single audio file was subclipped into each actual take, breaking apart the stringout, and saved as individual files. Those individuals files have since corrupted and are no longer playable within FCP, so I’m trying to use an MP4 of the cut we still have to identify which takes were actually used from the stringout. I’m hoping that there’s a way to match the “audio fingerprints” from the MP4 to the matching sections of the stringout.
Thanks for your help.

So a stringout against what is, basically, a finished cut?
You could try chopping up the finished cut line by line and then in PluralEyes doing a non-chonological sync (at least that’s what v2 calls it) to see what takes you used.
Unless you have hours of VO to go through, it may be an hour or two better well spent just to match by ear – trying to be too clever with solutions may waste more time than if you were to do the grunt work.

Yes, precisely that. Plural Eyes is a good suggestion, I’ll give it a shot. Otherwise, if I can’t tell the difference by ear, then why would the client? Thanks for the tips.
