numChannels

声道数。

sentSampleRate

发送本地音频的采样率，单位为 Hz。

sentBitrate

发送本地音频的码率平均值，单位为 Kbps。

txPacketLossRate

弱网对抗前本端到声网边缘服务器的丢包率 (%)。

internalCodec

内部的 payload 类型。

audioDeviceDelay

播放或录制音频时，音频设备模块的延迟 (ms)。

earMonitorDelay

耳返延迟 (ms)，即声音从麦克风输入到耳机输出的延迟。

aecEstimatedDelay

回声消除延迟 (ms)，即回声消除 (Acoustic Echo Cancellation, AEC) 模块测算出音频在本地播放前与被本地采集后的信号延迟。
