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
triangular-wave
profile (for mono outputs, a tremolo effect is obtained).
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", "Skew", and "Phase" controls), a value of 1 ("Wet") implies maximum panning
(full extent of the
"Rate", "Skew", and "Phase" controls) . |
| "Rate" slider | Adjusts the panning rate. |
| "Skew" slider | Adjusts the asymmetry of
the triangular-wave profile. A value of 0.5 implies a symmetrical profile.
All other values imply an asymmetrical ("sawtooth") profile, with the
"sense" of the asymmetry (i.e. whether the sawtooth rises quickly and falls slowly, or vice
versa) dependent on whether the "Skew" is greater than or less than 0.5.
|
| "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.

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).

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) |
