FYI - glad Audition will still be developed as a stand-alone product!
Soundbooth replaces Audition
Released as a beta in late 2006, Adobe Soundbooth is designed to enable creative professionals to produce high-quality audio. Offering the ability to quickly record, edit, and customize audio and music for web and video production, Adobe Soundbooth allows users to create pristine sound tracks. Soundbooth will replace Adobe Audition in the next version of Adobe Production Studio; however, Audition will continue to be developed for audio professionals as a stand-alone product for Windows (only).
