Two PSTN Line Positional “Receive” Audio Conferencing
This example creates a positional receive audio conferencing system using two
telephony lines to represent two remote participants. The system is called
“positional received” because the two remote participants will come from dif-
ferent loudspeakers to create a positional experience where one remote talker
comes from one loudspeaker and the other remote talker’s audio is associated
with the other loudspeaker system. The layout of the room may look like the
following figure with two zones of audio driving the ceiling loudspeakers.
This system will be designed to include eight table microphones, stereo pro-
gram audio, two telephony interfaces, and either a stereo amplifier or two
mono channel audio amplifiers.
