I, too, have been using Audition since back in the early days when it was Cool Edit Pro and still won't use anything else because I'm so familiar with the work flow. That being said and just as a heads-up, there is a well documented, and often bitched-about, bug with Audition 3 on Windows XP and Vista (don't know about Win 7 and it doesn't happen on all systems) that causes it to occasionally freeze up when previewing effects that you've implemented on tracks. The only way to "unfreeze" it, unfortunately, is to forcibly shut down Audition through the task manager. Adobe is well aware of the problem and issued a free patch for it but it works with varying degrees of success. Would be nice if they would just release a fixed version 4. Anyway, YMMV.
