Uniform Noise Panner 1

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 noise profile (for mono outputs, a tremolo effect is obtained). The random noise profile consists of a sequence of (pseudo-)random values, uniformly-distributed between 0 and 1. 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 (overrides the "Rate" and "Phase" controls), a value of 1 ("Wet") implies maximum panning (full extent of the "Rate" and "Phase" controls) .
"Rate" slider Adjusts the panning rate.
"Phase" slider Adjusts the relative "phase" between the left and right modulations (only effective for stereo outputs). A value of 0 implies complete "in-phase" correlation, i.e. the stereo image will be centered (no panning, just tremolo). A value of 1 implies maximal "out-of-phase" decorrelation , i.e. the stereo separation will be maximised. (See also the Uniform Noise Panner 2 component which is similar, but with extreme decorrelation. It has no "phase" control: the right modulation factor always equals one minus the left modulation factor)

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.
