I made this a while ago and roblox finally enabled audio waveforms so I can officially realase it.
Playback regions are very useful but difficult to edit, normally requiring trial and error. This plugin displays the audio waveform to use as a guide and lets you quickly preview changes, similar to wavepad.
It can also detect silence at the edges of the audio and automatically trim them with high accuracy.

I would appreciate any feedback or suggestions.
