Abstract


In this contribution, we embed full-duplex multichannel communication interfaces for tele-presence systems into a general framework. On the reproduction side, we consider a wide range of multichannel acoustic rendering techniques including traditional stereophony, '5.1' systems, and wave field synthesis using loudspeaker arrays for sound immersion. On the recording side, microphone arrays are discussed for capturing clean desired signals with spatial information. Based on this general framework, real-time implementations of such full-duplex multichannel communication systems are then described. We combine wave field synthesis with multichannel acoustic echo cancellation and adaptive beamforming and discuss a real-time implementation on standard desktop and laptop PCs.
