Detailed Description

Audio statistics of a remote user

Member Data Documentation

◆ uid

uint agora_gaming_rtc.RemoteAudioStats.uid

User ID of the remote user sending the audio streams.

◆ quality

int agora_gaming_rtc.RemoteAudioStats.quality

Audio quality received by the user.

◆ networkTransportDelay

int agora_gaming_rtc.RemoteAudioStats.networkTransportDelay

Network delay (ms) from the sender to the receiver.

◆ jitterBufferDelay

int agora_gaming_rtc.RemoteAudioStats.jitterBufferDelay

Network delay (ms) from the receiver to the jitter buffer.

◆ audioLossRate

int agora_gaming_rtc.RemoteAudioStats.audioLossRate

The audio frame loss rate in the reported interval.

◆ numChannels

int agora_gaming_rtc.RemoteAudioStats.numChannels

The number of channels.

◆ receivedSampleRate

int agora_gaming_rtc.RemoteAudioStats.receivedSampleRate

The sample rate (Hz) of the received audio stream in the reported interval.

◆ receivedBitrate

int agora_gaming_rtc.RemoteAudioStats.receivedBitrate

The average bitrate (Kbps) of the received audio stream in the reported interval.

◆ totalFrozenTime

int agora_gaming_rtc.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%.

◆ frozenRate

int agora_gaming_rtc.RemoteAudioStats.frozenRate

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

◆ totalActiveTime

int agora_gaming_rtc.RemoteAudioStats.totalActiveTime

The total time (ms) when the remote user in the Communication profile or the remote host in the Live-broadcast profile neither stops sending the audio stream nor disables the audio module after joining the channel.


◆ publishDuration

int agora_gaming_rtc.RemoteAudioStats.publishDuration

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


◆ qoeQuality

int agora_gaming_rtc.RemoteAudioStats.qoeQuality

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


◆ qualityChangedReason

int agora_gaming_rtc.RemoteAudioStats.qualityChangedReason

The reason for poor QoE of the local user when receiving a remote audio stream. See EXPERIENCE_POOR_REASON.


◆ mosValue

int agora_gaming_rtc.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.
