final case class Compander(rate: Rate, in: GE, ctrl: GE, thresh: GE = 0.5f, ratioBelow: GE = 1.0f, ratioAbove: GE = 1.0f, attack: GE = 0.01f, release: GE = 0.1f) extends SingleOut with Product with Serializable

A compressor, expander, limiter, gate and ducking UGen. This dynamic processor uses a hard-knee characteristic. All of the thresholds and ratios are given as direct values, not in decibels!

in

The signal to be compressed / expanded / gated.

ctrl

The signal whose amplitude controls the processor. Often the same as in, but one may wish to apply equalization or delay to it to change the compressor character (side-chaining), or even feed a completely different signal, for instance in a ducking application.

thresh

Control signal amplitude threshold, which determines the break point between slopeBelow and slopeAbove. Usually 0..1. The control signal amplitude is calculated using RMS.

ratioBelow

Slope of the amplitude curve below the threshold. If this slope > 1.0, the amplitude will drop off more quickly the softer the control signal gets; when the control signal is close to 0 amplitude, the output should be exactly zero -- hence, noise gating. Values < 1.0 are possible, but it means that a very low-level control signal will cause the input signal to be amplified, which would raise the noise floor.

ratioAbove

Slope of the amplitude curve above the threshold. Values < 1.0 achieve compression (louder signals are attenuated); > 1.0, you get expansion (louder signals are made even louder). For 3:1 compression, you would use a value of 1/3 here.

attack

The amount of time it takes for the amplitude adjustment to kick in fully. This is usually pretty small, not much more than 10 milliseconds (the default value). I often set it as low as 2 milliseconds (0.002).

release

The amount of time for the amplitude adjustment to be released. Usually a bit longer than attack; if both times are too short, you can get some (possibly unwanted) artifacts.
