Change MP3 file pitch

[Andronico]

Hello, I know that this question is not really about musical instruments, but I play guitar and have some good backing tracks in MP3 format that I use to play. The idea is change the pitch of these tracks and record with the new pitch in order to practice diferente scale positions with my portable MP3 player. Do anybody know any program to change the pitch and record to a new file ? Freeware, if it´s possible... Thanks. 🙂

Not freeware but Adobe Audition (Cool Edit Pro) can do it.

Never used the tool myself but worth a try:
