I think it uses kdenlive specific editing functions? And I do not know
enough about xml generated by cingg for making it work for us or guide its
author to do it..


but there are some python projects on github

https://github.com/align-videos-by-sound/align-videos-by-sound

https://github.com/benfmiller/audalign

in java

https://github.com/JorenSix/SyncSink



none of them (?) works as is for providing timecode offset for embedding in
media files so align via timecode will work, for example.

I'll keep searching! (there is related problem of aligning text with its
audio, but this is another area of research, it just showed up initially
via github search,)
