Detailed Description

Statistics of the remote audio.

Member Data Documentation

◆ uid

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.uid

ID of the user sending the audio streams.

◆ quality

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.quality

The receiving audio quality:

  • QUALITY_UNKNOWN(0): The quality is unknown.
  • QUALITY_EXCELLENT(1): The quality is excellent.
  • QUALITY_GOOD QUALITY_GOOD(2): The quality is quite good, but the bitrate may be slightly lower than excellent.
  • QUALITY_POOR(3): Users can feel the communication slightly impaired.
  • QUALITY_BAD(4): Users can communicate not very smoothly.
  • QUALITY_VBAD(5): The quality is so bad that users can barely communicate.
  • QUALITY_DOWN(6): The network is disconnected and users cannot communicate at all.

◆ networkTransportDelay

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.networkTransportDelay

The network delay from the sender to the receiver.

◆ jitterBufferDelay

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.jitterBufferDelay

The jitter buffer delay at the receiver.

◆ audioLossRate

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.audioLossRate

The packet loss rate in the reported interval.

◆ numChannels

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.numChannels

The number of channels.

◆ receivedSampleRate

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.receivedSampleRate

The sample rate (Hz) of the received audio stream, represented by an instantaneous value.

◆ receivedBitrate

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.receivedBitrate

The bitrate (Kbps) of the received audio stream, represented by an instantaneous value.

◆ totalFrozenTime

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.totalFrozenTime

The total freeze time (ms) of the remote audio stream after the remote user joins the channel. In a session, audio freeze occurs when the audio frame loss rate reaches 4% within two seconds.

◆ frozenRate

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.frozenRate

The total audio freeze time as a percentage (%) of the total time when the audio is available.

◆ mosValue

int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.mosValue

The quality of the remote audio stream as determined by the Agora real-time audio MOS (Mean Opinion Score) measurement method in the reported interval. The return value ranges from 0 to 500. Dividing the return value by 100 gets the MOS score, which ranges from 0 to 5. The higher the score, the better the audio quality.

The subjective perception of audio quality corresponding to the Agora real-time audio MOS scores is as follows:

| MOS score | Perception of audio quality | |--------------—|----------------------------------------------------------------------------------------------------------------------------------------------------------—| | Greater than 4 | Excellent. The audio sounds clear and smooth. | | From 3.5 to 4 | Good. The audio has some perceptible impairment, but still sounds clear. | | From 3 to 3.5 | Fair. The audio freezes occasionally and requires attentive listening. | | From 2.5 to 3 | Poor. The audio sounds choppy and requires considerable effort to understand. | | From 2 to 2.5 | Bad. The audio has occasional noise. Consecutive audio dropouts occur, resulting in some information loss. The users can communicate only with difficulty. | | Less than 2 | Very bad. The audio has persistent noise. Consecutive audio dropouts are frequent, resulting in severe information loss. Communication is nearly impossible. |

◆ totalActiveTime

long io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.totalActiveTime

The total time (ms) when the remote user neither stops sending the audio stream nor disables the audio module after joining the channel.

◆ publishDuration

long io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.publishDuration

The total publish duration (ms) of the remote audio stream.

◆ qoeQuality

long io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.qoeQuality

Quality of experience (QoE) of the local user when receiving a remote audio stream. See #EXPERIENCE_QUALITY_TYPE.
