The definition of the RemoteAudioStats struct, which reports the audio statistics of a remote user.
◆ RemoteAudioStats()
agora::rtc::RemoteAudioStats::RemoteAudioStats |
( |
| ) |
|
|
inline |
◆ uid
uid_t agora::rtc::RemoteAudioStats::uid |
User ID of the remote user sending the audio stream.
◆ quality
int agora::rtc::RemoteAudioStats::quality |
◆ networkTransportDelay
int agora::rtc::RemoteAudioStats::networkTransportDelay |
The network delay (ms) from the sender to the receiver.
◆ jitterBufferDelay
int agora::rtc::RemoteAudioStats::jitterBufferDelay |
The network delay (ms) from the receiver to the jitter buffer.
◆ audioLossRate
int agora::rtc::RemoteAudioStats::audioLossRate |
The audio frame loss rate in the reported interval.
◆ numChannels
int agora::rtc::RemoteAudioStats::numChannels |
◆ receivedSampleRate
int agora::rtc::RemoteAudioStats::receivedSampleRate |
The sample rate (Hz) of the remote audio stream in the reported interval.
◆ receivedBitrate
int agora::rtc::RemoteAudioStats::receivedBitrate |
The average bitrate (Kbps) of the remote audio stream in the reported interval.
◆ totalFrozenTime
int agora::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::rtc::RemoteAudioStats::frozenRate |
The total audio freeze time as a percentage (%) of the total time when the audio is available.
◆ mosValue
int agora::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.
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. |
