AudioEffect.Descriptor

public static class AudioEffect.Descriptor
extends Object

java.lang.Object
↳	android.media.audiofx.AudioEffect.Descriptor

The effect descriptor contains information on a particular effect implemented in the audio framework:

type: UUID identifying the effect type. May be one of: EFFECT_TYPE_AEC, EFFECT_TYPE_AGC, EFFECT_TYPE_BASS_BOOST, EFFECT_TYPE_ENV_REVERB, EFFECT_TYPE_EQUALIZER, EFFECT_TYPE_NS, EFFECT_TYPE_PRESET_REVERB, EFFECT_TYPE_VIRTUALIZER.
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.

Summary

Fields
`public String`	`connectMode` Indicates if the effect is of insert category `EFFECT_INSERT` or auxiliary category `EFFECT_AUXILIARY`.
`public String`	`implementor` Human readable effect implementor name
`public String`	`name` Human readable effect name
`public UUID`	`type` Indicates the generic type of the effect (Equalizer, Bass boost ...).
`public UUID`	`uuid` Indicates the particular implementation of the effect in that type.

Public constructors
`AudioEffect.Descriptor()`
`AudioEffect.Descriptor(String type, String uuid, String connectMode, String name, String implementor)`

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Fields

connectMode

Added in API level 9

String connectMode

Indicates if the effect is of insert category EFFECT_INSERT or auxiliary category EFFECT_AUXILIARY. Insert effects (typically an Equalizer) are applied to the entire audio source and usually not shared by several sources. Auxiliary effects (typically a reverberator) are applied to part of the signal (wet) and the effect output is added to the original signal (dry). Audio pre processing are applied to audio captured on a particular AudioRecord.

implementor

String implementor

Human readable effect implementor name

name

String name

Human readable effect name

type

UUID type

Indicates the generic type of the effect (Equalizer, Bass boost ...). One of EFFECT_TYPE_AEC, EFFECT_TYPE_AGC, EFFECT_TYPE_BASS_BOOST, EFFECT_TYPE_ENV_REVERB, EFFECT_TYPE_EQUALIZER, EFFECT_TYPE_NS, EFFECT_TYPE_PRESET_REVERB or EFFECT_TYPE_VIRTUALIZER.
For reverberation, bass boost, EQ and virtualizer, the UUID corresponds to the OpenSL ES Interface ID.

uuid

Added in API level 9

UUID uuid

Indicates the particular implementation of the effect in that type. Several effects can have the same type but this uuid is unique to a given implementation.
