and if you start with a script, this will dramatically reduce time/clip footage you'll invest to edit each. You'll still likely have to review the output of your script + make some. If the number of voices is low + vocal intonation of each speaker unique, you might be able to write a sox or ffmpeg script to pre-process your mixed audio track into separate speakers.

Once you've split the audio, you'll run the normalize + remix steps out of #1 above.ģ) If you plan on having many people on a recording, arrange for the raw recording to be done using 1x person/track initial recording for best quality + automated leveling/editing/remixing.Ĥ) Can Camtasia or any cheap/free tool do this? Unlikely.ĥ) If you have 1000s of hours of footage like this to unravel. Will audio quality drop very low on finalized/mastered product? Very likely. Is their any software that can do a good job of this. Will it be time consuming + expensive? Yes. then.Ĭan these people be separated into their own tracks? Yes.
