Yeah, when working with sounds it really is annoying to set up sounds. It’s usually a one time work to set up all resources, but sometimes, you just want to add one more sound 
When editor scripts were introduced I tinkered with them and it was one of the first thing I wanted to smoothen a bit with them. I made few scripts that utilise ffmpeg and ffprobe for playing, cutting and converting sounds from the Defold Editor:
It requires a bit of set up to work with your installation of FFMpeg, but once you make it, it’s pretty convenient when working with sounds.
I wish though that it would still be a built-in functionality for less friction
