Member Function Documentation

◆ getEffectsVolume()

double io.agora.rtc.IAudioEffectManager.getEffectsVolume ( )

Gets the volume of the audio effects.

The value ranges between 0.0 and 100.0.

Returns
  • Returns the volume, if the method call is successful.
  • < 0: Failure.

◆ pauseAllEffects()

int io.agora.rtc.IAudioEffectManager.pauseAllEffects ( )

Pauses all audio effects.

Returns
  • 0: Success.
  • < 0: Failure.

◆ pauseEffect()

int io.agora.rtc.IAudioEffectManager.pauseEffect ( int  soundId)

Pauses a specified audio effect.

Parameters
soundIdID of the audio effect. Each audio effect has a unique ID.
Returns
  • 0: Success.
  • < 0: Failure.

◆ playEffect() [1/2]

int io.agora.rtc.IAudioEffectManager.playEffect ( int  soundId,
String  filePath,
int  loop,
double  pitch,
double  pan,
double  gain 
)

Plays a specified audio effect.

Deprecated:
This method is deprecated. We recommend using the playEffect2 method to play the local audio effect.
Parameters
soundIdID of the specified audio effect. Each audio effect has a unique ID. If the audio effect is preloaded into the memory through the preloadEffect method, ensure that the soundID value is set to the same value as in the preloadEffect method.
filePathAbsolute file path of the audio effect file.
loopSets the number of times the audio effect loops:
  • 0: Plays the audio effect once.
  • 1: Plays the audio effect twice.
  • -1: Plays the audio effect in an indefinite loop until you call the stopEffect or stopAllEffects method.
pitchPitch of the audio effect. The value ranges between 0.5 and 2. The default value is 1 (no change to the pitch). The lower the value, the lower the pitch.
panSpatial position of the audio effect. The value ranges between -1.0 and 1.0.
  • 0.0: The audio effect displays ahead.
  • 1.0: The audio effect displays to the right.
  • -1.0: The audio effect displays to the left.
gainVolume of the audio effect. The value ranges betwwen 0.0 and 100,0. The default value is 100.0. The lower the value, the lower the volume of the audio effect.
Returns
  • 0: Success.
  • < 0: Failure.

◆ playEffect() [2/2]

int io.agora.rtc.IAudioEffectManager.playEffect ( int  soundId,
String  filePath,
int  loopCount,
double  pitch,
double  pan,
double  gain,
boolean  publish 
)

Plays a specified local or online audio effect file.

With this method, you can set the loop count, pitch, pan, and gain of the audio effect file and whether the remote user can hear the audio effect.

To play multiple audio effect files simultaneously, call this method multiple times with different soundIds and filePaths. We recommend playing no more than three audio effect files at the same time.

When the audio effect file playback is finished, the SDK triggers the onAudioEffectFinished callback.

Parameters
soundIdID of the specified audio effect. Each audio effect has a unique ID. If you preloaded the audio effect into the memory through the preloadEffect method, ensure that the soundID value is set to the same value as in the preloadEffect method.
filePathThe absolute file path (including the suffixes of the filename) of the audio effect file or the URL of the online audio effect file. For example, /sdcard/emulated/0/audio.mp4. Supported audio formats: mp3, mp4, m4a, aac. 3gp, mkv, and wav.
loopCountSets the number of times the audio effect loops:
  • 0: Plays the audio effect once.
  • 1: Plays the audio effect twice.
  • -1: Plays the audio effect in a loop indefinitely, until you call the stopEffect or stopAllEffects method.
pitchSets the pitch of the audio effect. The value ranges between 0.5 and 2. The default value is 1 (no change to the pitch). The lower the value, the lower the pitch.
panSets the spatial position of the audio effect. The value ranges between -1.0 and 1.0.
  • 0.0: The audio effect shows ahead.
  • 1.0: The audio effect shows on the right.
  • -1.0: The audio effect shows on the left.
gainSets the volume of the audio effect. The value ranges between 0.0 and 100,0. The default value is 100.0. The lower the value, the lower the volume of the audio effect.
publishSet whether or not to publish the specified audio effect to the remote stream:
  • true: The locally played audio effect is published to the Agora Cloud and the remote users can hear it.
  • false: The locally played audio effect is not published to the Agora Cloud and the remote users cannot hear it.
Returns
  • 0: Success.
  • < 0: Failure.

◆ preloadEffect()

int io.agora.rtc.IAudioEffectManager.preloadEffect ( int  soundId,
String  filePath 
)

Preloads a specified audio effect file into the memory.

Supported audio formats: mp3, aac, m4a, 3gp, wav.

Note
This method does not support online audio effect files.
Parameters
soundIdID of the audio effect. Each audio effect has a unique ID.
filePathAbsolute path of the audio effect file.
Note
To ensure smooth communication, limit the size of the audio effect file. We recommend using this method to preload the audio effect before calling the joinChannel method.
Returns
  • 0: Success.
  • < 0: Failure.

◆ resumeAllEffects()

int io.agora.rtc.IAudioEffectManager.resumeAllEffects ( )

Resumes playing all audio effects.

Returns
  • 0: Success.
  • < 0: Failure.

◆ resumeEffect()

int io.agora.rtc.IAudioEffectManager.resumeEffect ( int  soundId)

Resumes playing a specified audio effect.

Parameters
soundIdID of the audio effect. Each audio effect has a unique ID.
Returns
  • 0: Success.
  • < 0: Failure.

◆ setEffectsVolume()

int io.agora.rtc.IAudioEffectManager.setEffectsVolume ( double  volume)

Sets the volume of the audio effects.

Parameters
volumeVolume of the audio effects. The value ranges between 0.0 and 100.0 (default).
Returns
  • 0: Success.
  • < 0: Failure.

◆ setVolumeOfEffect()

int io.agora.rtc.IAudioEffectManager.setVolumeOfEffect ( int  soundId,
double  volume 
)

Sets the volume of a specified audio effect.

Parameters
soundIdID of the audio effect. Each audio effect has a unique ID.
volumeVolume of the audio effect. The value ranges between 0.0 and 100.0 (default).
Returns
  • 0: Success.
  • < 0: Failure.

◆ stopAllEffects()

int io.agora.rtc.IAudioEffectManager.stopAllEffects ( )

Stops playing all audio effects.

Returns
  • 0: Success.
  • < 0: Failure.

◆ stopEffect()

int io.agora.rtc.IAudioEffectManager.stopEffect ( int  soundId)

Stops playing a specified audio effect.

Parameters
soundIdID of the specified audio effect. Each audio effect has a unique ID.
Note
If you preloaded the audio effect into the memory through the preloadEffect method, ensure that the soundID value is set to the same value as in the preloadEffect method.
Returns
  • 0: Success.
  • < 0: Failure.

◆ unloadEffect()

int io.agora.rtc.IAudioEffectManager.unloadEffect ( int  soundId)

Releases a specified preloaded audio effect from the memory.
