Best and easiest software out there
I use Final Cut Pro and sometimes I have background noise like a computer or air conditioning. This software totally saved my audio and made it sound professional. There are multiple versions - one one their website which will work as a plugin, and this one which is stand alone. I like the stand alone because I just run my audio through this before importing, but if you want the plugin then make sure to get that version instead.
Stevehhhhhhhhh about SoundSoap 5, v5.0.0
