Properties

uid

User ID.

In the callback for the local user, uid is 0.
In the callback for remote users, uid is the ID of the remote user with the highest instantaneous volume (up to 3 users).

volume

User's volume, ranging from [0,255]. If the user mutes themselves (sets MuteLocalAudioStream to true) but audio capture is still enabled, the volume value indicates the volume of the locally captured signal.

vad

Note:

vad cannot report the voice activity status of remote users. For remote users, the value of vad is always 1.
To use this parameter, set reportVad to true when calling EnableAudioVolumeIndication.

Voice activity status of the local user.

0: No voice detected locally.
1: Voice detected locally.

voicePitch

Voice pitch of the local user (Hz). Value range: [0.0, 4000.0].

Note: voicePitch cannot report the voice pitch of remote users. For remote users, the value of voicePitch is always 0.0.
