Statistics of the remote audio.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.uid |
ID of the user sending the audio streams.
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. int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.networkTransportDelay |
The network delay from the sender to the receiver.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.jitterBufferDelay |
The jitter buffer delay at the receiver.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.audioLossRate |
The packet loss rate in the reported interval.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.numChannels |
The number of channels.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.receivedSampleRate |
The sample rate (Hz) of the received audio stream, represented by an instantaneous value.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.receivedBitrate |
The bitrate (Kbps) of the received audio stream, represented by an instantaneous value.
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.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.frozenRate |
The total audio freeze time as a percentage (%) of the total time when the audio is available.
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. |
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.
long io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.publishDuration |
The total publish duration (ms) of the remote audio stream.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.qoeQuality |
Quality of experience (QoE) of the local user when receiving a remote audio stream. See #EXPERIENCE_QUALITY_TYPE.
int io.agora.rtc2.IRtcEngineEventHandler.RemoteAudioStats.qualityChangedReason |
The reason for poor QoE of the local user when receiving a remote audio stream. See #EXPERIENCE_POOR_REASON.
