Parameters 
Description 
ID: Integer 
Effect ID. 
Delay: Double 
Specifies the delay of the filter (0.0 - 4.0). 
Depth: Double 
Specifies the depth of the filter (0.0 - 100.0). 
Feedback: Double 
Specifies the feedback of the filter (-99.0 - 99.0). 
Frequency: Double 
Specifies the frequency of the filter (0.0 - 10.0). 
Phase: Integer 
Specifies the phase angle. Use one of the following values. 0 for a phase shift of -180 degrees. 1 for a phase shift of -90 degrees. 2 for no phase shift. 3 for a phase shift of 90 degrees. 4 for a phase shift of 180 degrees. (0 - 4).  
WaveFormTriangle: Boolean 
Specifies the waveform type of the filter. Use True for a triangle waveform and False for a sine waveform. 
WetDryMix: Double 
Specifies the wet and dry mix of the filter (0.0 - 100.0). 

Flange, also called flanger, is an echo effect in which the delay between the original signal and its echo is very short and varies over time. The result is sometimes referred to as a sweeping sound. The term flange originated with the practice of grabbing the flanges of a tape reel to change the speed.
