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
• xCommand 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 (from the Audio Console)
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
• The TANDBERG Codec C90 sends and receives stereo signals
in multisite.
• The TANDBERG Codec C60/C40 will only send and receive
mono signals in multisite.
Examples 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.
