Member Function Documentation

◆ getStatistics()

virtual bool agora::rtc::IRemoteAudioTrack::getStatistics ( RemoteAudioTrackStats stats)
pure virtual

Gets the statistics of the remote audio track.

Parameters
statsA reference to the statistics of the remote audio track: RemoteAudioTrackStats.
Returns
  • true: Success.
  • false: Failure.

◆ getState()

virtual REMOTE_AUDIO_STATE agora::rtc::IRemoteAudioTrack::getState ( )
pure virtual

Gets the state of the remote audio.

Returns
The state of the remote audio: #REMOTE_AUDIO_STATE.

◆ registerMediaPacketReceiver()

virtual int agora::rtc::IRemoteAudioTrack::registerMediaPacketReceiver ( IMediaPacketReceiver packetReceiver,
aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

Registers an IMediaPacketReceiver object.

You need to implement the IMediaPacketReceiver class in this method. Once you successfully register the media packet receiver, the SDK triggers the onMediaPacketReceived callback when it receives an audio packet.

Parameters
packetReceiverThe pointer to the IMediaPacketReceiver object.
Returns
  • 0: Success.
  • < 0: Failure.

◆ unregisterMediaPacketReceiver()

virtual int agora::rtc::IRemoteAudioTrack::unregisterMediaPacketReceiver ( IMediaPacketReceiver packetReceiver)
pure virtual

Releases the IMediaPacketReceiver object.

Parameters
packetReceiverThe pointer to the IMediaPacketReceiver object.
Returns
  • 0: Success.
  • < 0: Failure.

◆ registerAudioEncodedFrameReceiver()

virtual int agora::rtc::IRemoteAudioTrack::registerAudioEncodedFrameReceiver ( IAudioEncodedFrameReceiver packetReceiver,
aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

Registers an IAudioEncodedFrameReceiver object.

You need to implement the IAudioEncodedFrameReceiver class in this method. Once you successfully register the media packet receiver, the SDK triggers the onEncodedAudioFrameReceived callback when it receives an audio packet.

Parameters
packetReceiverThe pointer to the IAudioEncodedFrameReceiver object.
Returns
  • 0: Success.
  • < 0: Failure.

◆ unregisterAudioEncodedFrameReceiver()

virtual int agora::rtc::IRemoteAudioTrack::unregisterAudioEncodedFrameReceiver ( IAudioEncodedFrameReceiver packetReceiver)
pure virtual

Releases the IAudioEncodedFrameReceiver object.

Parameters
packetReceiverThe pointer to the IAudioEncodedFrameReceiver object.
Returns
  • 0: Success.
  • < 0: Failure.

◆ setRemoteVoicePosition()

virtual int agora::rtc::IRemoteAudioTrack::setRemoteVoicePosition ( float  pan,
float  gain,
aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

Sets the sound position and gain

Parameters
panThe sound position of the remote user. The value ranges from -1.0 to 1.0:
  • 0.0: the remote sound comes from the front.
  • -1.0: the remote sound comes from the left.
  • 1.0: the remote sound comes from the right.
gainGain of the remote user. The value ranges from 0.0 to 100.0. The default value is 100.0 (the original gain of the remote user). The smaller the value, the less the gain.
Returns
  • 0: Success.
  • < 0: Failure.

◆ adjustDecodedAudioVolume()

virtual int agora::rtc::IRemoteAudioTrack::adjustDecodedAudioVolume ( int  decoded_index,
int  volume,
aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

Sets the volume of each audio decoded channel

Parameters
decoded_indexThe channel index of the remote user. The value ranges from 0 to 100:
volumeThe channel index of the remote user. The value ranges from 0 to 100.
  • 0: mute the channel.
  • 100: keep the origin volume of the channel.
Returns
  • 0: Success.
  • < 0: Failure.

◆ muteRemoteFromTimestamp()

virtual int agora::rtc::IRemoteAudioTrack::muteRemoteFromTimestamp ( uint32_t  timestamp)
pure virtual

mute remote stream from timestamp

Note
  • unmuteRemoteFromTimestamp should be called after muteRemoteFromTimestamp, othewise this stream will be muted all time
Parameters
timestampThe rtp timestamp of start mute
Returns
  • 0: Success.
  • < 0: Failure.

◆ unmuteRemoteFromTimestamp()

virtual int agora::rtc::IRemoteAudioTrack::unmuteRemoteFromTimestamp ( uint32_t  timestamp)
pure virtual

unmute remote stream from timestamp

Note
  • unmuteRemoteFromTimestamp should be called after muteRemoteFromTimestamp, othewise this stream will be muted all time
Parameters
timestampThe rtp timestamp of start unmute
Returns
  • 0: Success.
  • < 0: Failure.

◆ adjustAudioAcceleration()

virtual int agora::rtc::IRemoteAudioTrack::adjustAudioAcceleration ( int  percentage,
aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

set percentage of audio acceleration during poor network

Note
  • The relationship between this percentage and the degree of audio acceleration is non-linear and varies with different audio material.
Parameters
percentageThe percentage of audio acceleration. The value ranges from 0 to 100. The higher the percentage, the faster the acceleration. The default value is 100 (no change to the acceleration):
  • 0: disable audio acceleration.
  • > 0: enable audio acceleration.
Returns
  • 0: Success.
  • < 0: Failure.

◆ adjustAudioDeceleration()

virtual int agora::rtc::IRemoteAudioTrack::adjustAudioDeceleration ( int  percentage,
aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

set percentage of audio deceleration during poor network

Note
  • The relationship between this percentage and the degree of audio deceleration is non-linear and varies with different audio material.
Parameters
percentageThe percentage of audio deceleration. The value ranges from 0 to 100. The higher the percentage, the faster the deceleration. The default value is 100 (no change to the deceleration):
  • 0: disable audio deceleration.
  • > 0: enable audio deceleration.
Returns
  • 0: Success.
  • < 0: Failure.

◆ enableSpatialAudio()

aosl_ref_t  ares = AOSL_REF_INVALID 
)
pure virtual

enable spatial audio

Parameters
