Exceptional for the Price, 2008-05-26 Great functionality for a basic audio editor. All the function and none of the fluff. It works well in Leopard. My only gripe was the error messages sent to the user don't explain what I'm doing wrong in the software. Once you figure the work around for the issues everything moves very seamlessly. When I worked more on PC I used Sonic Foundry for the majority of my creative audio work. Now on a Mac, Peak has been the best on that Platform.
