Local stereo circuit example with API commands
The graphic gives a picture of how to configure the audio system for recording a stereo presentation. You can do the same from the API. The
belonging xCommands and xConfigurations are listed below.
In this example there is a local input with input id 5 and a local output with output id 6. Both are set to stereo by the channels parameter.
•
xCommand Audio LocalInput Update Inputid:5 Name:”Presentation” MixerMode:Fixed AGC:On Mute:Off Channels:2
•
xCom mand Audio LocalOutput Update Outputid:6 Name:”Recorder” Loudspeaker:No Channels:2
•
xConfiguration Audio Input Line 1 Channel: Left
•
xConfiguration Audio Input Line 2 Channel: Right
•
xConfiguration Audio Output Line 3 Channel: Left
•
xConfiguration Audio Output Line 4 Channel: Right
Presentation
The local input has two connectors: Line 1 and Line
2. When these two connectors are mixed together as
a stereo signal, Line 1 is the left channel and Line 2 is
the right channel.
Recorder
The local output has two connectors: Line 3 and Line
4. The local output pans the stereo signal according
to the channel configuration of the connectors. Line
3 receives the left channel and Line 4 receives the
right channel.
Local stereo circuit example
Stereo
Stereo in point to point call
Receive stereo
If the other participant sends stereo the codec will receive stereo. To
play stereo the local output still needs to be configured correctly (see
local stereo circuit example).
Transmit stereo
In order to send stereo, the other participant must be able to receive
stereo. Also, the local input with the stereo signal must be configured
correctly (see local stereo circuit example). In addition, there must be
a signal on one of the connectors connected to the local input.
Stereo in Multisite
Stereo in Multisite on Codec C90
The TANDBERG Codec C90 also sends and receives stereo signals
in multisite.
Stereo in Multisite on Codec C60
The TANDBERG Codec C60 will only send and receive mono signals
in multisite.
Example of local stereo configuration
When you want to record a stereo presentation the audio system can
be configured as shown in the illustration.
In the example the local input has two connectors: Line 1 and Line
2. When these two connectors are mixed together as a stereo signal,
Line 1 is the left channel and Line 2 is the right channel.
And the local output has two connectors: Line 3 and Line 4. The local
output pans the stereo signal according to the channel configuration
of the connectors. Line 3 receives the left channel and Line 4 receives
the right channel.
