The gain of the transfer curve at its knee: soft at the minimum, hard at zero.
At 0 dB of input gain, the knee lies at 0 dBFS.
release 10.0 µs to 1.00 s
The time constant of the envelope detector’s release stage. At the minimum
value, r4 acts like a distortion.
output −12 dB to 0 dB
The level at which a steady 0 dBFS input leaves r4.
displays
gain reduction 0 dB to 40 dB
How far the input signal exceeds the threshold of the limiter core. It holds
the largest reduction since the input, knee, or release last changed. Its color
temperature increases with the predicted amount of distortion.
transfer curve
How the input and output signals move along the transfer curve. It has the
same color temperature as the gain reduction meter.
