The remote participants at site 2 will see the site 1 talker at microphone 1 on
the right side of their screen when the remote talkers are looking at the screen
because the site 1 talker at microphone 1 is on the “right” side of the camera
from the camera’s perspective.
By transmitting positional audio of talker 1 biased to the right channel to the
remote site, it is possible to make the local talker at microphone 1 sound as if
they were coming from the “room right” loudspeaker to reinforce their visual
location as shown in the following figure.
The relative position of talker 1 left or right on the screen depends on the rela-
tive positioning of the talker with respect to the camera reference point.
To determine the relative positioning relative to the camera, draw a line from
the microphone to the camera reference plane as shown in the previous figure.
In this example microphone 1 is panned to approximately 0.4 right (assuming
the edge of the room is considered 1.0) relative to the camera location. The
exact amount of panning can be increased to create a wider spatial presence at
the remote site.
