Parameters 
Description 
ID: Integer 
Effect ID. 
Feedback: double 
Specifies the feedback of the filter (0 - 100.0). 
LeftDelay: double 
Specifies the left delay of the filter (1.0 - 2000.0). 
RightDelay: double 
Specifies the right delay of the filter (1.0 - 2000.0). 
PanDelay: double 
Specifies the pan delay of the filter (0 - 1). 
WetDryMix: double 
Specifies the wet and dry mix of the filter (0.0 - 100.0). 
panDelayUseMax 
Use maximum pan delay. 

An echo effect causes sounds to be repeated after a fixed delay, usually at a diminished volume. As the repeated sounds are fed back into the mix, they are repeated again.
