2.2.3. Clock
These parameters are configurable from the "Preferences" page , in "Audio" menu, "Clock".
●
Click on "Configure" button to be able to modify the parameters.
Clock source : The IQOYA can synchronized on the digital audio input or on the internal clock of the
●
codec. With the internal clock selected, the AES receiver uses a sampling frequency converter of 125 dB.
One can also select a Network Clock source in case of network audio connectivity. Specific configuration
settings for LiveWire and AES67 Connectivity is detailed in a later chapter.
●
Master Clock : Select PTP Master clock or None.
Sampling frequency (Hz) : This parameter defines the working sampling frequency of the IQOYA
●
platform. If AES In clock is selected, the sampling frequency must corresponds to the detected clock.
Note that received and generated IP streams can carry audio at a different sampling frequency (in which
case a high quality frequency change is applied).
○
When sampling frequency is set to 48 kHz, IP streams can be at 48 kHz, 32 kHz, 16 kHz (G722),
and 8 kHz (G711). Note that 44.1 kHz is allowed for a HTTP stream
○
When sampling frequency is set to 44.1 kHz, IP streams must be at 44.1 kHz.
●
Activate AES IN SRC : This parameter is only effective in Internal Clock mode.
2.2.4. Synchronous AoIP In and Synchronous AoIP Out
These pages concern the configuration of network audio input and output.
Specific configuration settings for network audio such as AES67 / LiveWire Connectivity is detailed in a later
chapter.
