AudioEffect.OnEnableStatusChangeListener The OnEnableStatusChangeListener interface defines a method called by the AudioEffect when a the enabled state of the effect engine was changed by the controlling application. 
BassBoost.OnParameterChangeListener The OnParameterChangeListener interface defines a method called by the BassBoost when a parameter value has changed. 
EnvironmentalReverb.OnParameterChangeListener The OnParameterChangeListener interface defines a method called by the EnvironmentalReverb when a parameter value has changed. 
Equalizer.OnParameterChangeListener The OnParameterChangeListener interface defines a method called by the Equalizer when a parameter value has changed. 
PresetReverb.OnParameterChangeListener The OnParameterChangeListener interface defines a method called by the PresetReverb when a parameter value has changed. 
Virtualizer.OnParameterChangeListener The OnParameterChangeListener interface defines a method called by the Virtualizer when a parameter value has changed. 
Visualizer.OnDataCaptureListener The OnDataCaptureListener interface defines methods called by the Visualizer to periodically update the audio visualization capture.
