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 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 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 identifying the effect type.
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.
DynamicsProcessing	DynamicsProcessing is an audio effect for equalizing and changing dynamic range properties of the sound.
DynamicsProcessing.BandBase	Base class for bands
DynamicsProcessing.BandStage	Base class for stages that hold bands
DynamicsProcessing.Channel	Class for Channel configuration parameters.
DynamicsProcessing.Config	Class for Config object, used by DynamicsProcessing to configure and update the audio effect.
DynamicsProcessing.Config.Builder
DynamicsProcessing.Eq	Class for Equalizer stage
DynamicsProcessing.EqBand	Class for Equalizer Bands Equalizer bands have three controllable parameters: enabled/disabled, cutoffFrequency and gain
DynamicsProcessing.Limiter	Class for Limiter Stage Limiter is a single band compressor at the end of the processing chain, commonly used to protect the signal from overloading and distortion.
DynamicsProcessing.Mbc	Class for Multi-Band Compressor (MBC) stage
DynamicsProcessing.MbcBand	Class for Multi-Band compressor bands MBC bands have multiple controllable parameters: enabled/disabled, cutoffFrequency, attackTime, releaseTime, ratio, threshold, kneeWidth, noiseGateThreshold, expanderRatio, preGain and postGain.
DynamicsProcessing.Stage	base class for the different stages.
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.
HapticGenerator	Haptic Generator(HG).
LoudnessEnhancer	LoudnessEnhancer is an audio effect for increasing audio loudness.
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	This class was deprecated in API level 35. use the `Spatializer` class to query the capabilities of the platform with regards to spatialization, a different name for audio channel virtualization, and the `AudioAttributes.Builder.setSpatializationBehavior(int)` to characterize how you want your content to be played when spatialization is supported.
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.
Visualizer.MeasurementPeakRms	A class to store peak and RMS values.
