I plan on editing the Death Night's voice by filtering it through various audio effects in my studio until I achieve the desired effect.

However it doesn't look like it's going to be so easy to actually get at the voice audio files. I found voice.cmp here:
C:\Program Files\LarianStudios\Beyond Divinity Demo\Acts\Act1\Voice

And then there are .dlg and .gsm files which describe all the voices that can be heard throughout the demo.

So does anyone know how to edit/extract from these files?
