The Kjaerhus Audio Classic Compressor is a piece of free software available as a VST plug-in. I no longer run this plug-in in my current suite as I now run Pro Tools instead of Cubase, which is what I was running this with before. The process of downloading and installing this plug-in shouldn't take too long as it is an easy step by step process. The interface of the plug-in is very straight forward and just contains the familiar compression parameters including those for threshold, ratio, knee, attack, release, and output level. As most users can probably tell, those who are familiar with traditional compression parameters will feel right at home here. I don't think a manual is necessary for any part of this plug-in, but haven't seen one so I can't speak to it's make up.

SUITABILITY/PERFORMANCE

When I ran the Kjaerhus Audio Classic Compressor plug-in I did so in Cubase SX 2.0 primarily, and later in Cubase 3. The computer I was running it on was a Hewlett Packard Pavilion dv8000 lap top with a 3.0 Ghz processor and 2 GB of RAM. I don't recall ever having an issue running this plug-in, as it doesn't take up very much processing power. It isn't like I was running one or two at a time either, as many times I had a whole bunch of these going within a single session. Most users won't have a problem running this, but since it's free there isn't any harm in trying as every system is different.

OVERALL OPINION

When I was running the Kjaerhus Audio Classic Compressor it was a plug-in that I used quite often. For a free plug-in, it's even more impressive. While I don't know how much I would use this now if I had it in my Pro Tools rig as I have superior sounding compressors in my current rig, but when I didn't have as much to work with, this one often came in handy. I'd encourage anyone with a DAW that is VST compatible to download the Kjaerhus Audio Classic Compressor, as you really don't have anything to lose!
