Used Karaoke Surgeon for Windows?
Developer’s Description
KS utilizes formant preservation to reduce or eliminate the chipmunk/munchkin sound that can develop when key change is applied to audio with vocals. KS uses the same high quality audio algorithm used in its other products to ensure high quality, distortion free audio after key and/or tempo change. And most importantly, any file with lyrics, when saved or converted, will retain the lyrics.
