I used audition before it was bought by adobe, and it was a very good audio editor. But today, almost anything is better than audition. A wonderful, if a bit ugly and “raw” DAW is Reaper. I use it for everything. The big contenders are Ableton Live and Apple Logic Pro. A lot of people, that create music, are using them. I like reaper the most because it is nimble and is still pretty complete.
