Abstract:

While higher order ambisonic approaches can be used to generate multiple zone soundfields, this paper adopts a Least Squares matching approach which provides a more flexible formulation. The base approach, adopted from [1] computes speaker weights which allow for the placement of single sources in the soundfield. In this paper the approach is extended firstly to two multi-frequency sources and then to narrowband speech signals. The results for multi-frequency sources explore the zonal soundfield errors resulting from varied source positions. For speech signals, the approach provides a potential solution for multiple conversation reproduction in a multi user environment. The paper results indicate that the approach is feasible for zones which do not suffer occlusion effects from other zones. However, for more versatile multizone soundfield reproduction a 3D approach is recommended. © 2011 IEEE.
