Not Bad - Can't beat the price
I use it for the "Ask the podcast coach" show to level out the volumes of callers, remove noise, etc. Good stuff. This is something I do days in advance of actually needing or editing the file. It does take a bit and if you're sitting and waiting, it seems like forever. Also, much like the free "levelator" software it is not a miracle worker. If you have "some" noise, and "some" deviation in volume levels it will work fine. As always, try to get the volumes set as you record (and then you don't need this). I played with their app and was surprised how well it polished the built in microphone of my iphone. It was "listenable" audio.
