Source Type = IP service, and IP service is UDP
In UDP mode, the audio format has to be declared.
- Right channel only: compares the right channel samples to the silence threshold. In
case the sample values are always lower to the silence threshold during the defined
silence duration, silence condition is reached.
- Left and right channels: compares both the left and right channel samples to the
silence threshold. In case the sample values on both channels are always lower to the
silence threshold during the defined silence duration, silence condition is reached.
- At least one channel: compares both the left and right channel samples to the silence
threshold. In case the sample values on at least one of the two channels are always
lower to the silence threshold during the defined silence duration, silence condition is
reached.
Read/Write Silent audio is defined through these two parameters, expressed in dBfs.
When audio level is below the threshold value during at least the defined duration, the
alarm "Analog audio in silent" or "Digital audio in silent" is set (if it is enabled from the
"Alarms setup" menu).
Read/Write Audio signal is defined through the three parameters. Audio signal is considered as
recovered if all the following conditions are true:
●
●
Note the following rule: Signal drop duration <= (Signal duration / 2).
Once signal is recovered, the alarm "Analog audio in silent" or "Digital audio in silent" is
reset (if it is enabled from the "Alarms setup" menu).
IQOYA X/LINK range user manual
Audio level exceeds the Signal threshold (dBfs) within the "Signal duration"
analysis window (ms).
Audio level does not stay below the Signal threshold during the "Signal drop
duration", within the "Signal duration" analysis window.
