Parameters 
Description 
ID: Integer 
Effect ID. 
Bandwidth: Double 
Specifies the bandwidth of the equalizer (1.0 - 36.0). 
Center: Double 
Specifies the center frequency of the equalizer (80.0 - 16000.0). 
Gain: Double 
Specifies the gain of the equalizer (-15.0 - 15.0). 

A parametric equalizer amplifies or attenuates signals of a given frequency. Parametric equalizer effects for different pitches can be applied in parallel by setting multiple instances of the effect on the same buffer. In this way, the application can have tone control similar to that provided by a hardware equalizer.
