Drum Compression...
I've gotten good results compressing all of the drum tracks....
The snare & Bass I compress a little for a touch of added sustain (longer release/depends on tempo) Usually it works out so there's just enough compression to sorta level out any majorly wild volume changes. Maybe 6-12 db threshold below average peak and possibly up to 2/1 ratio. No drummer is perfect. Especially me.
On the overheads, once again I *MIGHT* compress just a little. Just enough to remove any major unwanted volume changes if any.
I have found that compressing the tracks really brightens up the 'ess'ing in the cymbals, so I either try to multi-band compress the cymbals back down, de-ess, or EQ the cymbals back down. Usually between 5-10k depending on the cymbal/mic location.
For some reason, compression sounds better to me mixed back through an aux too...
Better to play & mic the drums the way you want them to sound first! This is ideal, but no drummer is perfect. Especially me.
A lot of people spend $$$$$ on mics, pre's, and compression for their sound. I am one of those people. Then I found that half or more of my sound was where I was putting the mics and what my drum room sounded like. Imagine my horror in buying my high dollar mics and getting almost the same sound out of them. Hmmm time to mess with the room & placement.
Every recording is different... Get us a link of your stuff for further discussion...
