im just looking to get rid of the vocals on a certain track and also cut it down in length. the file is in m4a format and i need a free, check it FREE, way to edit it. any help would be appreciated.
Just convert it to mp3 or wav (which can be done in itunes). It will make your life much easier, I promise.

Then you can edit it in any recording program. (If you don't have any software to do this, get Audacity, which I think is the free one that's available...)
