Random Telegraph Panner 2

Functional Description
Auto-panning effect which creates a time-varying stereo separation by re-distributing the input signal to the stereo outputs, according to a random telegraph profile (for mono outputs, a tremolo effect is obtained). The random telegraph profile alternates between 0 and 1, with a (pseudo)-random distribution of change-points. The outputs are modulated according to the settings in the Parameter Window, as summarised in the following table.

Parameter Purpose
"Mix" slider Adjusts the amount of panning. A value of 0 ("Dry") implies no panning. A value of 1 ("Wet") implies maximum panning, whereby when the left channel is active, the right is silent, and vice versa, thereby maximising the stereo separation.
"Rate" slider Adjusts the panning rate.

See also the Random Telegraph Panner 1 component which is similar, but has an additional "phase" control for adjusting the relative distribution of the signals sent to the left and right channels.

Algorithm
The panning is implemented by amplitude modulation according to the stored profile. The profile is scanned using a table-lookup oscillator algorithm (see [Moore] chapter 3.1.7 for further information). See [HRM] for general information on audio effects.
