This dual stage release is something I've only seen on paid plugins. So short hits like a snare, can have a quick release, whereas the track as a whole can be managed with an independent release time. The idea behind this dual release stage is to treat short transients differently from the overall RMS of the material. The crest control allows you to set the threshold for each of the two release stages. It features a clean and well made GUI, two release stages (Peak and RMS) and a 'delta' control which lets you listen to the difference between the compressed portion of your signal and the original.

It is not an emulation of any particular compressor, but it's features are more akin to what you'd see on a high end digital mastering compressor. The TDR's Compressor is one of the most transparent mastering compressors you'll come across regardless of price. They produce excellent sounding and stable plug-ins that come in VST, AU & AXX, 32 & 64-bit. This list is some of my personal favorites, the ones I use the most. Occasionally a free plugin bests just about everything out there. Many cheap or even free plugins are extremely good. But rest assured, price is not always an indicator of quality.

There are a lot of things that contribute to the cost of a plugin.
