Not sure if anyone else ever commented on this , but I was having issues where my sound files would pick up static. The static wasn't in the source file or in the edited copy. Didn't matter if I used WAV or MP3. Would eventually show up in my music files and became a real problem with short sound files. (Those less than a second.)
Upgraded my version of AGS from 3.2.1.111 to 3.3.2 and the problem with static went away.
This isn't a request for help, more of documenting a known problem and fix.
