6.19 Audio
Audio
You can set the gain of the audio signals to suit your specific requirements. The live video
image is shown in the window to help you check the audio source. Your changes are effective
immediately.
If you connect via Web browser, you must activate the audio transmission on the
'Live'
functions page. For other connections, the transmission depends on the audio settings of the
respective system.
The audio signals are sent in a separate data stream parallel to the video data, and so increase
the network load. The audio data is encoded according to the selected format and requires
additional bandwidth. If you do not want any audio data to be transmitted, select
Off .
Input volume
Set the input volume using the slide. Values range from 0 to 119.
Line Out
Set the line output gain using the slider. Values range from 0 to 115.
Recording format
Select a format for audio recording. The default value is AAC 48 kbps . You can select AAC 80
kbps , G.711 or L16 depending on the required audio quality or sampling rate.
AAC audio technology is licensed by Fraunhofer IIS.
