Adobe Audition for the Mac is based on a new underlying architecture, to create an audio editing environment for fine tuning single files or creating multi-track mixes. It has various audio ‘sweetening’ tools to help users address problems in recordings to create usable soundtracks. www.adobe.com/go/audition_labs.

The major changes to Adobe Audition for the Mac are a new, faster audio playback engine, native multi-channel support for 5.1 surround sound, noise reduction and restoration capabilities, and new audio effects including de-hummer, de-esser and volume leveler.  Adobe Audition has real time effect stacking, extended automation and the ability to perform bounces in the multi-track editor.
