Adobe also has a more powerful program called Adob
Audition, but Soundbooth is not intended to replace
this. It is instead aimed at creative professionals who do no
specialize in audio or people who need a simple editin
program and do not require the full features of AdobeAudition.
The major difference in both of the programs is that
Soundbooth uses a task based interface and AdobeAudition uses a tool based interface.
