I seem to have lost my transport controls on edit mode for adobe audition 2. How do I get
it back to the way it should be? Also, where can I buy updated versions of adobe audition?
You've probably just covered up the transport controls - it's not that difficult to do. Just shift a few panes around along the bottom, and they'll probably reappear.
You can't purchase a perpetual Audition licence any more - you have to rent the software through the Creative Cloud. If you look around this forum, you will find plenty of comments about that...
