FXAlg #716: Quad MovDelay
Each of these two algorithms offers generic monaural moving delay lines in a dual mono algorithm. Each separate
moving delay can be used as a flanger, chorus, or static delay line selectable by the LFO Mode parameter. Both
flavors of chorus pitch envelopes are offered: ChorTri for triangle, and ChorTrap for trapzoidal pitch shifting. Refer
to the Chorus section of this book (FXAlgs #150-153) for more information on these envelope shapes.
Each moving delay offers control over center delay length, LFO excursion, LFO rate, feedback, and high frequency
damping. The delay length, in milliseconds, is the center of LFO excursion. LFO excursion is controlled by the LFO
Dpth parameter in percent. LFO Depth is an arbitrary value, and is the percentage of available excursion. When
using LFO Mode Flange, this adjusts the range that the LFO will move the delay tap. When in LFO Mode ChorTri
or ChorTrap, this controls the maximum pitch depth caused by the moving delay tap, and is constant regardless of
LFO Rate.
Input
Both of these algorithms are configured with dual mono control meaning the left and right channels are set up to
be completely independent of each other. In Dual MovDelay, each channel has a single moving delay segment.
Parameters beginning with ÒLÓ and ÒRÓ control the left and right input channels respectively.
