The Audio Param EQ Effect is used to alter the frequency response of an audio system using linear filters.
 
| Property: | Function: | 
|---|---|
| Center freq | The frequency in Hertz where the gain is applied (range 20.0 to 22000.0, default = 8000.0 Hz). | 
| Octave Range | The number of Octaves over which the gain is applied (Centered on the Center Frequency) (range 0.20 to 5.00, default = 1.0 octave). | 
| Frequency Gain | The gain applied (range 0.05 to 3.00, default = 1.00 - no gain applied). | 
The graph shows the effect of the gain to be applied over the frequency range of the audio output.
