hi there, is there any free programs that you know where i can edit an mp3 file? Im talking about turning down the voice and turning up the guitar and such. thanks
you might want to try Audacity. Its free and you can use several different effects on the audio, im not sure specifically if you can lower vocals

If you want to take a commercially released song and do that... it's impossible. You can't separate the different tracks and change the levels as it'a already been mixed into two channels.
