android.media.audiofx

Provides classes that manage audio effects implemented in the media framework.

Interfaces

AudioEffect.OnControlStatusChangeListener The 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.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. 

Classes

AcousticEchoCanceler Acoustic Echo Canceler (AEC). 
AudioEffect AudioEffect is the base class for controlling audio effects provided by the android audio framework. 
AudioEffect.Descriptor The 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, EFFECT_AUXILIARY or {at_link #EFFECT_PRE_PROCESSING}
  • name: human readable effect name
  • implementor: human readable effect implementor name
The method queryEffects() returns an array of Descriptors to facilitate effects enumeration. 
AutomaticGainControl Automatic Gain Control (AGC). 
BassBoost Bass boost is an audio effect to boost or amplify low frequencies of the sound. 
BassBoost.Settings The Settings class regroups all bass boost parameters. 
EnvironmentalReverb A sound generated within a room travels in many directions. 
EnvironmentalReverb.Settings The Settings class regroups all environmental reverb parameters. 
Equalizer An Equalizer is used to alter the frequency response of a particular music source or of the main output mix. 
Equalizer.Settings The Settings class regroups all equalizer parameters. 
NoiseSuppressor Noise Suppressor (NS). 
PresetReverb A sound generated within a room travels in many directions. 
PresetReverb.Settings The Settings class regroups all preset reverb parameters. 
Virtualizer An audio virtualizer is a general name for an effect to spatialize audio channels. 
Virtualizer.Settings The Settings class regroups all virtualizer parameters. 
Visualizer The Visualizer class enables application to retrieve part of the currently playing audio for visualization purpose.
