The Chameleon Labs 7720 is an SSL quad-compressor-type rack-mount unit. I recorded the entirety of October River with an actual SSL 2-channel mix compressor. They're nice.
And they were/are like $6000. And now you can get one for $535.
You might be wondering why you might want a compressor for recording in digital. In the olden days compressors were needed to deal with the fact that laquer/analog tape has very limited dynamic range and a compressor helps you hear the quiet stuff while not overloading on the loud stuff. But then engineers found that nice compressors can make stuff sound awesome.
So do you want these kinds of limiters when you record? I dunno. We have plenty of dynamic range to deal with so why not just do all your compression later? I dunno. But that's certainly what we've been doing.
Lately I've been using the Waves emulation of a Urei LA-2A compressor on every instrument in the mix. Yup, not the 1176. Not even the Fairchild emulation does it for me. But the LA-2A emulation just works for me.
Uh. So that's all I've got.
