I tried the demo. It's one of the better compressors I've used. Bearing in mind I'm a hobbyist with limited mixing abilities.
I recently tried a heap of compressor demos from developers big and small and loads of freeware. This and PSP Audioware FetPressor stood out from the pack. I was looking for something that sounded good with minimum tweaking, and I found it in Comprime.
It's hard to make this sound thing bad, It's easy to dial in and achieve quick results. It sounds smooth and rounded. You can really push this thing hard and it still sounds great.
