Fraunhofer IDMT presented in 2005 a sound reinforcement system based on the precedence effect that could recreate the natural spatial impression of static and dynamic sources on the stage regardless of the position of the listeners. Based on the experience learned over the last years, this paper presents three different developments for this system. These improvements are related to the automatic determination of the configuration parameters, the multiuser adjustment of fine parameters on the tribune using portable devices, and a new room simulation approach that takes into consideration both source and listener’s dependencies.
