Adobe Audition CS6

Engineer professional sounding audio with this premier platform independent audio editing tool.
 
When it comes to internet audio, clean, clear and well balanced sound is now the standard, regardless of what you're doing. Podcasts, internet radio and other streamed audio needs to sound like it was done in a real sound studio, or getting consistent listeners may be difficult to do. This is one of the reasons why I like Adobe Audition. It’s a platform independent audio editing tool.
 
Adobe Audition CS5.5 delivers the professional tools you need to make your audio and video productions sound their best. It handles a wide range of audio production tasks efficiently, including recording, mixing, and sound restoration. With native support for OS X and windows, you can record, mix, edit, and master your audio with a powerful audio toolset.
 
Adobe Audition CS5.5 has an improved audio processing engine. With it, you'll experience greater speed throughout the audio production process whether opening and saving files, processing multicore effects, or simultaneously editing multiple sessions. With roundtrip editing with Adobe Premiere Pro, the audio in your video clips will be greatly improved.  You can pass individual clips and multi-track mixes from Adobe Premiere Pro CS5.5 software to Adobe Audition for editing, or send Adobe Premiere Pro sequences with a reference video to Adobe Audition for complete soundtrack creation.

Pros: Improved audio engineer, multiplatform support.

Cons: Slightly expensive for an audio scrubber.
 
Conclusion: Adobe Audition offers some really nice audio editing tools.  It’s a professional level package, and as such, may not be intuitive to everyone right out of the box.  While the price is at about the industry average for a package of this caliber and type, it is a bit on the expensive side, so if you're purchasing this for one or two immediate need projects it may not be the right choice if cost is a concern. 
 
Adobe's integration with other audio and video packages from its CS5.x suite makes this a logical buy, however, if repeated audio editing is in your immediate future.
