Public NotInheritable Class BASS_BFX_AUTOWAH

The BASS_BFX_AUTOWAH type exposes the following members.

	Name	Description
	BASS_BFX_AUTOWAH	Default constructor
	BASS_BFX_AUTOWAH(Single, Single, Single, Single, Single, Single)	Constructor already setting the members
	BASS_BFX_AUTOWAH(Single, Single, Single, Single, Single, Single, BASSFXChan)	Constructor already setting the members

	Name	Description
	Preset_Default	Sets the instance members to a preset.
	Preset_FastAutoWah	Sets the instance members to a preset.
	Preset_HiFastAutoWah	Sets the instance members to a preset.
	Preset_SlowAutoWah	Sets the instance members to a preset.

	Name	Description
	fDryMix	Dry (unaffected) signal mix (-2...+2). Default = 0.
	fFeedback	Feedback (-1...+1). Default = 0.
	fFreq	Base frequency of sweep range (0<...1000). Default = 0.
	fRange	Sweep range in octaves (0<...<10). Default = 0.
	fRate	Rate of sweep in cycles per second (0<...<10). Default = 0.
	fWetMix	Wet (affected) signal mix (-2...+2). Default = 0.
	lChannel	A BASSFXChan flag to define on which channels to apply the effect. Default: -1 (BASS_BFX_CHANALL) - all channels.

The effect implements the auto-wah by using 4-stage phaser effect which moves a peak in the frequency response up and down the frequency spectrum by amplitude of input signal.

The fDryMix is the volume of input signal and the fWetMix is the volume of delayed signal. The fFeedback sets feedback of auto wah (phaser). The fRate and fRange control how fast and far the frequency notches move. The fRate is the rate of sweep in cycles per second, fRange is the width of sweep in octaves. And the the fFreq is the base frequency of sweep.
