Ok, I need to experiment more with this.

A strong noise? That happens with mono files, > ATM, due to lazyness/"not implemented yet" ;) stereo should work It was stereo and sounded like a pitching artefact. I'll try to provide some comparison sound files. It was there even though I didn't change the pitch, which I think should be possible to make _very_ transparent even if the processing is active so I'm hoping it is fixable.
