Panners:
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.
A value of 1 ("Wet") implies maximum panning, whereby
the right channel modulation factor is set to one minus the
left channel modulation factor, thereby maximising the stereo separation.
|
| "Rate" slider | Adjusts the panning rate. |
See also the
Uniform Noise 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.
Signal Implementations
| Audio signals | Control signals | Description |
|---|
| Single input single output mono-mono | n/a | Mono input is modulated, sent to mono output (tremolo effect) |
| Single input single output mono-stereo | n/a | Mono input is modulated with separate gains, then sent to stereo output (auto-panning effect) |
| Single input single output stereo-mono | n/a | Stereo inputs are modulated with separate gains, then averaged and sent to mono output (tremolo effect) |
| Single input single output stereo-stereo | n/a | Stereo inputs are modulated with separate gains, then sent to stereo output (auto-panning effect) |
| Double input single output mono-mono | n/a | Mono inputs are modulated with separate gains, then averaged and sent to mono output (tremolo effect) |
| Double input single output mono-stereo | n/a | Mono inputs are modulated with separate gains, then sent to stereo output (auto-panning effect) |
