FXAlg #964: Dual AutoPanner
A dual mono auto-panner
Allocation Units:
2
"Dual AutoPanner" is a 2-PAU dual mono auto-pan effect. Left and right inputs are treated as two mono signals
which can each be independently auto-panned. Parameters beginning with ÒLÓ control the left input channel, and
parameters beginning with ÒRÓ control the right input channel. Autopanning a mono signal consists of choosing an
axis offset, or Origin, as the center of LFO excursion, then adjusting the desired excursion amount, or PanWidth.
Note that the PanWidth parameter is a percentage of the available excursion space after Origin is adjusted. If Origin
is set to full left (-100%) or full right (100%) then there will be no room for LFO excursion. Control of six different
LFO shapes (see the section of this book on FXAlgs #961-962), variable center attenuation, and a rate scaler that
scales LFO rate into the audible range for a new flavor of amplitude modulation effects are also provided for each
channel.
Final image placement can be seen on the bottom right of the PARAM2 and PARAM3 pages respectively for left
and right input channels. The moving mark represents the location of each channel within the stereo field.
