Gives out a binary-valued (0 or 1) control signal depending on the absolute value of the input audio signal compared with the "Threshold" slider setting. Specifically, if the input audio signal exceeds the threshold, the output control signal is set to one, otherwise the output control signal is set to zero. This component can be used for a variety of purposes ranging from a "signal presence detector" or "trigger" to a simple noise gate (i.e. by multiplying the audio signal by the output of this component). For stereo input audio signals, the average of the absolute values of the left and right channels is used in the comparison with the threshold setting.
Floating-point arithmetic.
