Definitely looking forward to having more reliable and synchronized audio when working with lipsyncing, sounds like a great step in the right direction with the animation tools. Great work!
Unfortunately I’ll have to hold off on direct feedback or testing as I’m not currently running Linux on any of my animation work computers. But ill leave some generic feedback:
Scrubbing and clicking producing snippits of audio is great and will help with lipsyncing a lot. Not sure if it needs to be adjustable in playback length if you can find the sweet spot. Flash had a good snippet length back in those days but I’d have to go investigate to see how long those snippets actually were.
