## Field Documentation

## ◆ numChannels

int numChannels

The number of audio channels.

## ◆ sentSampleRate

int sentSampleRate

The sampling rate (Hz) of sending the local user's audio stream.

## ◆ sentBitrate

int sentBitrate

The average bitrate (Kbps) of sending the local user's audio stream.

## ◆ internalCodec

int internalCodec

The internal payload codec.

## ◆ txPacketLossRate

unsigned short txPacketLossRate

The packet loss rate (%) from the local client to the Agora server before applying the anti-packet loss strategies.

## ◆ audioDeviceDelay

int audioDeviceDelay

The audio device module delay (ms) when playing or recording audio.

## ◆ audioPlayoutDelay

int audioPlayoutDelay

The playout delay of the device

## ◆ earMonitorDelay

int earMonitorDelay

The ear monitor delay (ms), which is the delay from microphone input to headphone output.

## ◆ aecEstimatedDelay

int aecEstimatedDelay

Acoustic echo cancellation (AEC) module estimated delay (ms), which is the signal delay between when audio is played locally before being locally captured.
