Acoustic echo cancellation with headphones

A media coverage on the demo in Computer World available here.but echo thing is a must, you have to have this checked. The prototype system was shown at MSR TechFest 2009. now heres the trick, double click on the mic again and go to enhancements and you have to check echo cancellation thing, mess around with rest of options see if youll like it or not.

Comparison of audio spatialization over headphone: audio wave with alternating mono and spatial.Comparison of audio spatialization over a pair of speakers: mono wave and spatialized wave.Paper РІР‚Сљ Multichannel Acoustic Echo Cancelation in Multiparty Spatial Audio Conferencing With Constrained Kalman Filtering,РІР‚Сњ in Proceedings of the International Workshop on Acoustic Echo and Noise Control (IWAENCРІР‚в„ў08), Seattle, WA, September 2008.We will also demonstrate the AEC capability in real time so that the remote side will only hear the near-end participantРІР‚в„ўs speech without their own echoes. This is proven to significantly improve conferencing experience since each participant could easily differentiate the current remote talker and focus on the content being discussed.Р”Р‡urthermore, Multichannel AEC (Acoustical Echo Cancellation) is a crucial component to enable quality audio experience during conferencing, especially without headset. We have built and will demonstrate technologies to enhance user experience in multiparty conferencing using highly realistic and immersive spatial audio, with both loudspeakers and headphones. This is in sharp contrast to what happens in real life where each voice has its distinct location. Current commercial systems mix them into a single mono audio stream, and thus all voices of remote participants will sound like coming from the same location when using loudspeakers or from inside the listenerРІР‚в„ўs head when using headphones. In multiparty conferencing, one hears voices of more than one remote participants.
