I'm looking for an audio editing program that can modify the speed of an audio file but at the same time distorts the pitch accordingly. Like what "sound recorder" does "increase by 100", but I want to increase it onl by 20. I know programs like audacity can speed up sound files but they don't distort the pitch accordingly. So does anyone know of another program that can do this? Or maybe a way to hack into sound recorder to make it speed up by 20% only instead of 100%?
