Interfaces

AudioEffect.OnControlStatusChangeListenerThe OnControlStatusChangeListener interface defines a method called by the AudioEffect when a the control of the effect engine is gained or lost by the application  
AudioEffect.OnEnableStatusChangeListenerThe 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.OnParameterChangeListenerThe OnParameterChangeListener interface defines a method called by the BassBoost when a parameter value has changed. 
EnvironmentalReverb.OnParameterChangeListenerThe OnParameterChangeListener interface defines a method called by the EnvironmentalReverb when a parameter value has changed. 
Equalizer.OnParameterChangeListenerThe OnParameterChangeListener interface defines a method called by the Equalizer when a parameter value has changed. 
PresetReverb.OnParameterChangeListenerThe OnParameterChangeListener interface defines a method called by the PresetReverb when a parameter value has changed. 
Virtualizer.OnParameterChangeListenerThe OnParameterChangeListener interface defines a method called by the Virtualizer when a parameter value has changed. 
Visualizer.OnDataCaptureListenerThe OnDataCaptureListener interface defines methods called by the Visualizer to periodically update the audio visualization capture. 

Classes

AudioEffectAudioEffect is the base class for controlling audio effects provided by the android audio framework. 
AudioEffect.DescriptorThe effect descriptor contains information on a particular effect implemented in the audio framework:
  • type: UUID corresponding to the OpenSL ES interface implemented by this effect
  • uuid: UUID for this particular implementation
  • connectMode: EFFECT_INSERT or EFFECT_AUXILIARY
  • name: human readable effect name
  • implementor: human readable effect implementor name
The method queryEffects() returns an array of Descriptors to facilitate effects enumeration. 
BassBoostBass boost is an audio effect to boost or amplify low frequencies of the sound. 
BassBoost.SettingsThe Settings class regroups all bass boost parameters. 
EnvironmentalReverbA sound generated within a room travels in many directions. 
EnvironmentalReverb.SettingsThe Settings class regroups all environmental reverb parameters. 
EqualizerAn Equalizer is used to alter the frequency response of a particular music source or of the main output mix. 
Equalizer.SettingsThe Settings class regroups all equalizer parameters. 
PresetReverbA sound generated within a room travels in many directions. 
PresetReverb.SettingsThe Settings class regroups all preset reverb parameters. 
VirtualizerAn audio virtualizer is a general name for an effect to spatialize audio channels. 
Virtualizer.SettingsThe Settings class regroups all virtualizer parameters. 
VisualizerThe Visualizer class enables application to retrieve part of the currently playing audio for visualization purpose.
