It's one of those things where you blink and you almost miss it, but part of Adobe's CS5.5 announcement earlier today includes the news that Adobe is finally releasing its Audition software. Adobe Soundbooth, its Mac-only audio toolset, has reached end-of-life status, and development and sales will cease April 24. A beta version of Adobe Audition for the Mac was released in November.

Soundbooth users on CS3, CS4 or CS5 can upgrade to Adobe Audition CS5.5 for US$99. Those who upgrade their Production Premium or Master Collection will automatically have full access to the software. Normal retail price of Audition will be $349.
