I need to know which software to purchase to be able to make an album where my customers can go to specific tracks such as song one, song 2, song 3 etc yet have them all in one album
Any DAW (Digital Audio Workstation) that allows you to burn CDs. mp3 files cannot contain the track marking information that is needed to jump between track without having each of them as a separate file.
Of course Audition is an ideal choice for recording, multitracking, editing and mastering for CD. But doesn't have MIDI support if you need to use VST instruments or sample sounds.
