I've been using Audition 1.5 since it was called CoolEdit, before Adobe bought it. I also have 3.0 and 5.5, which are progressively more complex.

The computer with 1.5 is WinXP, and everything works. There are issues when 1.5 is paired with Win7, though, and Adobe no longer supports 1.5 at all, just as Microsoft has dropped support for XP.

A problem I face as a book narrator is that ACX (Audiobook Creation Exchange) won't accept the Fraunhofer Mp3's created by Audition 1.5. ACX, for some reason, requires us to record the chapters as wav files, then convert to Mp3. I've been recording on 1.5, then going to 5.5 for conversions.

My new killer souped -up studio computer is sitting in a box, waiting for me to finish a current project before all the connecting and installing begins. (The adage about horses and streams applies here.)

So it will be farewell Audition 1.5, which is an outstanding program that got left behind by two corporations out-tweaking each other.

NOTE: Audition as a brand is being dumped. You can get fully-featured 3.0 free. Just Google some keywords...
