While there are a number of DAWs that will do the job, Pro Tools ensures you’ll play nice with the rest of the world. You’ll need some specialized plugins to go in and out of FCP easily. From the early 90s I worked with a Sonic Solutions DAW, but finally went to Pro Tools because I got tired of having to justify its use to prospects unfamiliar with it.
