Abstract
Distributed performances of musicians at distant locations are recently enjoying increasing interest due to the availability of larger bandwidths in network and mobile communication. Modern spatial audio capturing and multichannel reproduction techniques could make these performances an immersive and more realistic experience. But a bidirectional acoustic coupling of rooms introduces disturbing echo loops, which calls for Acoustic Echo Cancellation (AEC) methods. This contribution investigates the Frequency Domain Adaptive Kalman Filter, a state-of-the-art AEC algorithm, in a novel and practical context of a distributed music performance including an Ambisonics audio rendering. In particular, the possibility of using ambisonic channels as reference signals for the echo canceling algorithm is investigated, which allows a significant reduction of the algorithm's computational load.
