# Fuzzpilz Oppressor 2

Oppressor 2 is a compressor/gate.

Parameter | Explanation
--- | ---
Pregain | Preamp gain.
Mode | Level detection mode.
Attack | How quickly Oppressor 2 reacts to increases in the input level.
Decay | How quickly Oppressor 2 reacts to decreases in the input level.
Threshold | Threshold level.
Gate Ratio | Gate (expander) ratio. Basically, the level will be lowered further according to this if it's under the threshold; If the input level is -5 dB with a threshold of 0 dB and the gate ratio is 2.2, for example, the output level will be -11 dB.
Gate Knee | Gate (expander) knee "softness". Higher values generally result in a smoother response.
Comp Ratio | Compressor ratio. The signal will be attenuated by this ratio if it's above the threshold; for example, if the input level is 10 dB with a threshold of 0 dB and the compressor ratio is 4.0, the output level will be 2.5 dB.
Comp Knee | Compressor knee "softness". Higher values generally result in a smoother response.
Stereo | Stereo bleed applied before level calculation; this works similarly to e.g. jComp's Stereo Link attribute. If this parameter is set to "Full link" (all the way to the right), changes in level on any one channel affect both channels equally; if it's set to "No link" (all the way to the left), they affect only their own channel.
Bypass | Not sure what this does. Maybe it performs complicated surgery on you. Maybe it just bypasses the gate and compressor. One of those, anyway.
Inertia | How smoothly the machine responds to parameter changes.
Resolution | Gain is calculated once every n samples, where n is the value of this parameter; in the meantime, there's linear interpolation. Move this further to the left if you think it's worth the added CPU consumption.
Postgain | Postamp gain.

Oppressor 2 does sidechaining using Buzz's somewhat obscure input handling system instead of the auxbus like Oppressor. Right click → Manage Inputs. I don't think I'll have to explain how this dialogue works; but if you're going to use this feature, I recommend using two ch.amps or do-nothings for this instead of setting each input up manually.
