For high-quality multimedia communication systems, such as tele- conferencing, or tele-teaching (especially of music), multichannel sound reproduction is highly desirable. While current approaches still rely on a restrained listening area, the sweet spot, a volume solution for a large listening space is offered by the Wave Field Synthesis (WFS) method, where arrays of loudspeakers generate a prespecified soundfield. On the recording side of the two-way sys- tems, the use of microphone arrays is an effective approach to cope with undesired signal components in the receiving room. However, before full-duplex communication can be deployed, efficient ap- proaches to the acoustic echo cancellation (AEC) problem in this challenging scenario have to be found. In this paper, we investigate different options for system integration, after a brief discussion of the current state of the art. We then present a first real-time so- lution on a regular PC platform, based on an efficient AEC for MIMO (multi-input and multi-output) systems in the frequency- domain. |
