The Nomad Factory Essential Compressor is a simple compression plug-in that is a part of the Essential Studio Suite bundle of plug-ins. This plug-in is a great way to get a bunch of good plug-ins at a very cheap price per plug-in as there's nine plug-ins in total. It's an easy process to install the full bundle of these plug-ins, just make sure you do so keeping proper compatibility in mind. This is a really simple compressor in the sense that it's got all of the familiar parameters for a compressor, so if you're familiar with the make up of traditional compressors, you won't have a problem here. It's got sliders for threshold, ratio, attack, release, and gain make up, as well as a built in limiter mode. It also has input and output leveling parameters. No manual is necessary here - if something is unclear I'd recommend doing some research on compressors in general.
I've got the Nomad Factory Essential Compressor and the full Essential Suite running at home on my Pro Tools LE rig. I've got a Mac Book Pro lap top that has a 2.2 Ghz Intel Core 2 Duo processor and 4 GB of RAM, and I've got Pro Tools LE 8 running with a Digi 002R audio interface. This system is definitely enough to run the plug-in more than comfortably, as none of the Essential plug-in take up very much processing power.
While not the best sounding compression plug-in that I've got in my suite at home, the Nomad Factory Essential Compressor is still adequate for getting simple compression done. It's a pretty clean sounding compressor, but definitely doesn't add a whole lot of depth or warmth as you'd get with some other compression plug-ins. This entire bundle is great for those who are just putting together a DAW and want some cheap, quality plug-ins. Nomad has some great plug-ins to offer, so getting this bundle is a great place to start if you're interested in them. This isn't the best sounding compression plug-in Nomad has to offer, but in the context of this bundle it's pretty much a steal...
