can anyone help please,ive been told that i need to drop the keys on all my backing tracks,anyone got any idea how i can do this..they are all on ipod and laptop.
I use Goldwave wave editor for doing this. Audacity will do the same thing of course.
I guess it's the same principle. Your mp3 is loaded as a wave file, then it can be manipulated for pitch change. I do find that anything much more than a semitone or two either way can result in a rather less than natural sound.
