Update: For a comparison of features included in Audition 3, CS5.5 and CS6, see this table. For what's new and changed in Audition CS6, see this page.

Adobe Audition CS5.5 brings the best features from Adobe audio products into a single cross-platform package. It focuses on high performance in post-production workflows. Some features in the Windows version of Adobe Audition 3.0 are not available in CS5.5.

The product team is actively soliciting feedback about which features are top customer priorities through a public survey. Adobe also encourages you to submit additional feature requests, which the team regularly reviews when planning future versions.

Tip: For a list of top new features, see What's New in Adobe Audition CS5.5. If you'd like to take advantage of new CS5.5 features without losing functionality from Adobe Audition 3.0, consider installing both versions.
