Transpose complete song on 1 track

Hi, i am doing a little project for a friend as follows, i have converted a batch of mp4 karaoke files to mp3, now what i need to do is import the mp3 into a single track,(i know how to do this lol) but then i want to transpose the whole song to fit the singers vocal range either up or down(if that makes sense) the easiest way please.
any advice is truly appreciated
Thank you

thanks, this is for multiple tracks, i suppose the same principle will be for a single track?

Yes, same thing can be done on a single track. I’m sure that you are aware that transposing a track like this might deteriorate the sound quality of it. Especially if transposed more than 1 semitone.

thank you
