Adobe Soundbooth
« »Soundbooth is a new audio editor from Adobe. The beta version was released this weekend on Adobe labs. It includes audio effects, sound creation, sound removal, audio cleanup functions, and more. No MP3 export in this free beta release (due to licensing cost), so you'll have to export as WAV and then convert the WAV to MP3 with Audacity. The final, paid version will include MP3 export capabilities.
