There’s a right way and a wrong way to change the key of a backing track. Before you do it (or pay any company out there to do it for you) make sure you know they’re doing it right because if they cut corners and do it the cheap/wrong way, you’ve wasted your money (you could have done it just as well yourself for free)…
Hi, Is there any way I can alter the key to your tracks. Normally I use Midifles and Cakewalk or Van Basco. Thanks
The most inexpensive way to change the key of audio tracks is to use a karaoke player (hardware or software) to pitch-shift the song to a different key.
While doing it this way costs you nothing, the downside is that pitch-shifting affects the quality of the audio so is ok for karaoke but far from acceptable for a professional act.
The proper way to do it is have the key changed from the master arrangement and re-recorded in to the key you want it in from scratch. This way is much more professional and keeps the full quality of the track (because you are, in effect, having a brand new track created in that particular key).
