class FFlanger

Type	Name	Description
float	CenterDelayMsec
FDelay	DelayBuffer	Internal delay buffer.
float	DelayedSignalLevel
float	DelaySample	Delay sample generated from LFO per block.
FSinOsc2DRotation	LFO	Internal LFO for delay amount.
float	MixLevel	Balance between original and delayed signal (Should be between 0 and 1.0; 0.5 is equal amounts of each and

0.5 is more delayed signal than non-delayed signal) |

float	ModulationDepth	Modulation depth is clamped to CenterDelayMsec to avoid clipping.
float	ModulationRate	LFO parameters LFO frequency
float	NonDelayedSignalLevel
float	SampleRate	The audio sample rate, Init() must be called to initialize this.
FAlignedFloatBuffer	ScratchBuffer	Scratch buffer used for accumulating delay samples per block.
