If I have a video where the audio from two mics is uneven - so one participant sounds a lot quieter than the other - is there a very low effort magic trick I can play on that video to boost the quiet sound? I don't have separate tracks

So far I've dug around in iMovie and Descript and Audacity and ffmpeg and fiddled with feature called things like "loudnorm" and "normalize" and "compressor" without success, but I have no idea what I'm doing so it may just be I haven't figured out how to apply whichever of those is the right option

@simon I've done this manually with EQ/volume/compressor but it's annoyingly fiddly to do well, I'd try something like auphonic.com as lazy attempt first

@simon I'm doing a ton with camtasia. It's closed source, subscription afaik but it can do it:

@rugk @ame @simon Hi :)
Please just let us know if you have any questions about Auphonic!

@simon Maybe the autoleveler from auphonic.com/features#leveler is able to help here. But seperate tracks would make it easier for sure 😅.

@simon Do the speakers (mostly) take turns? If so, it shouldn't be all that difficult to boost the quiet segments.

@simon If you're using Audacity then its Limiter feature can do this. For a low effort workflow try: 1. Normalise to 0dB, 2. Effect > Plugin > Limiter > Soft Limiter (use defaults), 3. Normalise to -1dB.

You might try using something like autoeditor?

But to answer your question more directly, if you can split the track into segments either by using silence or some fancy AI thing that can detect the turn-taking then you only need to apply normalize to each segment separately and it should be even
