Audio commands
xCommand Audio Diagnostics MeasureDelay
This command will measure the audio delay/latency in a device connected to the video system.
A typical use case it to measure the delay in a TV connected to the video system via the HDMI
connector. If the delay in a TV is too high, the real-time experience of a video call will be
substantially degraded. If the delay is more than 50 ms we recommend the user to find a TV
setting that has shorter delay. Typical TV settings that can reduce the delay are: Gaming Mode
and PC Mode.
This command will measure the delay between output and input (microphone). This means
that if you are using an external acoustic echo canceller or audio mixer, this command will also
measure the delay of these devices.
Requires user role: ADMIN, USER
USAGE:
xCommand Audio Diagnostics MeasureDelay [MeasurementLength: MeasurementLength]
[Output: Output] [Volume: Volume]
where
MeasurementLength : Integer (1..100)
The length of the measurement in number of seconds. In a noisy environment a longer
measurement time will give a more reliable and robust result.
Outp ut : HDMI/Line/Internal/All
HDMI: Measure the delay of the device connected to the HDMI output.
Line: Measure the delay of the device connected to the Line output (only available on
video systems that have a Line output).
Internal: Measure the delay of the internal loudspeaker (only available on video systems
that have an internal loudspeaker).
All: Will measure the maximum delay of all outputs.
Volume : Integer (1..50)
The volume for the test signal. In a noisy environment a higher volume gives more
reliable and robust results.
xCommand Audio Microphones Mute
Mute all microphones.
Requires user role: INTEGRATOR, USER
USAGE:
xCommand Audio Microphones Mute
xCommand Audio Microphones ToggleMute
Toggle the microphone between muted and unmuted.
Requires user role: INTEGRATOR, USER
USAGE:
xCommand Audio Microphones ToggleMute
xCommand Audio Microphones Unmute
Unmute all microphones.
Requires user role: INTEGRATOR, USER
USAGE:
xCommand Audio Microphones Unmute
