How to slow down an Mp3 file?
I am using Garageband 10.0.3
I can't follow most of the tutorials online on how to slow down an Mp3 file. I have pressed "Control Option G," my LCD view is set to "beats and project," but I can't find the match tempo and pitch option shown in online tutorials. When I increase or decrease the tempo, the clip appears to stretch or shrink, but the playback is the same. Can anyone help me slow down an Mp3? It seems that this should be a simple thing to do.
Thanks
