After reading this thread: What audio editor are you using?, I was dooing a little research to choose the best audio editor for mac and pc (I need a cross-platform editor). But I would love to have the Pro Tools shuttle mode workflow in an audio editor. There is a scrub function in Adobe Audition, but it's not that powerfull like shuttle mode. Maybe somebody found that function in an audio editor?
Reaper, hands down the most flexible editor and also with fully configurable scrub modes. Cross-platform is just the beginning of the benefits.
