Abstract
We describe two methods for sound field reconstruction which can be used for splitting the sound field coming from two different sources in space. The methods provide a constructive scheme to separate for example two voices recorded simultaneously by a synchronized array of microphones for which the location of the speakers in space approximately known. The first method is based on the potential approach of Kirsch-Kress and has been first suggested by Ben-Hassen and Potthast [3]. The second method is based on Potthast's Point Source Method [2], where we propose a new version which can be used for source splitting. For both methods we describe the basic derivation steps and discuss convergence, numerical realization and stabilization aspects. ©2008 IEEE.
