Acoustic Massive Multichannel Systems

Multichannel sound reproduction enhances sound realism in virtual reality and multimedia communication systems, e.g. teleconferencing. To enable hands-free fullduplex communication based on massive multichannel sound reproduction and capturing, efficient adaptive systems are required. The project aims at development a real-time massive multichannel acoustic echo canceller prototype.
