Since some commercial product is gone (such as Maxon's PluralEyes) and a recent updated version (now with prebuild Windows binary) finally out after more than 5 years, we wanna share it:

Official git: https://github.com/protyposis/AudioAlign/
Download link: https://github.com/protyposis/AudioAlign/releases/
.NET SDK 6 (needed): https://dotnet.microsoft.com/en-us/download/visual-studio-sdks

 

Interesting tool, but it needs a lot of work.
I did a small test with two different audio sources. The app was able to sync the audio fine, however it sounded with pitch fluctuations, meaning that the stretching or shrinking to match the base audio is not working well. It needs to compensate the pitch to adjust the different speed changes.
It is interesting to hear that none of those problems happen in the demo videos.

Bump.

There are many interesting improvements in recent both Aurio and AudioAlign releases, check them out:

Aurio v4.2.1

Aurio v4.2.0

AudioAlign v1.7.0

AudioAlign v1.6.1

AudioAlign v1.6.0

It's still "young" and surelly has some bugs, but its developer (Mario Guggenberger) is pretty active recently and fairly inclined to fix users-reported issues, so don't hesitate to report problems (or needs):
