Running Audacity for Mac, current or relatively current version. Apple has a multi-band compressor plugin.
There are three crossovers with different frequencies available. It seems to default to a low bass (200Hz), low-midrange (900Hz) and midrange (4000Hz)
There are also settings for "pre-gain" and "post-gain". What is that intended to do? I understand what gain is, I just don't understand how that applies to this.
Then there are settings for each of the crossover freqs:
Threshold
Headroom
EQ
I understand that "threshold" is going to be the normal compressor threshold- the threshold at which the compressor starts to activate. But what do "EQ" and "headroom" mean, in this context? The EQ is just a slider, from -20 to 20dB. Headroom goes from .01 to 40dB
I'm trying to compress a board feed with a bunch of loud snare hits. It seems to be working well to my ears, but I'd like to know what I'm actually doing....
