FL4TT3RY is a gentle and flattering compressor intended for use on busses, but which also works well on individual channels. It's inspired by (but not strictly modelled on) a specific hardware compressor, which shall remain nameless.

Features:

• Very soft knee which gradually ramps up the ratio until (eventually) reaching limiting.
• RMS based level detection, with a window size that varies depending on the attack time.
• Powerful envelope shaping with no calibration for the time constants: use your ears.
• Switchable high-pass filter for the sidechain.
• Switchable asymmetric soft clipping to prevent overs.
• Zero latency.
• Low CPU use.
