Feature request: sound compare

[Kaltxi]

Nice work on the tool!

That said lately I've been missing a feture to compare not just the picture, but sound too. A basic simultaneous sund playback would be awesome already to try and hear shifts by ear, but a more sophiscticated overlay of waveforms would be even better.

Thanks for the suggestion.

Audio is going to add a whole new layer of complexity, and I can't decide if it's the right thing for video-compare or not. Personally, I'm not going to work on this, but if someone wants to take a crack at it and send me a PR for basic synced audio support, please do so.
