Hey Lucas, doing okay over here. Thank you for asking. Good to hear back from you.
You can always try the Loopsmith demo first which gives you five free exports, so you can put it through its paces on your setup. If the demo runs well under Wine, the paid version will behave the same.
Are you also using Windows as well with your setup?
Since Godot is your engine, this just went up and might be a useful article: https://www.austinhaynesmusic.com/godot-wav-loop-points
Whenever you get the chance to try it, it would be interesting to see how it goes on Linux, good or bad.
All the best.
