Have you designed a large system for video or audio teleconferencing that looked straightforward and simple on paper, but turned out to be a configuration nightmare after it was wired up? Or perhaps you've even had to re-design the entire system to make it work properly? If you answered yes to either of these questions, help is on the way.

By using these basic connection and process flow ideas, you can simplify general routing requirements in the room, make it easier to manage echo cancellation references, and get the best system echo cancellation performance when using dynamic feedback controllers in a conferencing environment. The following design tip will help you optimize multi-unit audio DSP systems for video and audio teleconferencing applications using the internal audio data bus more efficiently.

Tip #1: Simplify echo cancellation reference management by connecting all far-end audio sources and local program audio to the same physical DSP unit.

Echo cancellation, the enabling technology for teleconferencing, is simply the process of preventing unwanted audio from passing through a microphone channel to the far end. For example, we want audio from talkers in the local room to pass to the far end, but we don't want that same audio coming from the far end to return to the far end because that's the “echo” we want to cancel.
