The use of wave field synthesis (WFS) enables the correct localization of virtual sources over a large listening area. While point sources outside the listening area can be accurately reconstructed, sources inside the listening area can be correctly perceived from certain positions only. To avoid these limitations, we continuously optimize the selection of the involved speakers and the signal processing in real-time based on a tracked user position. In addition, user tracking enables us to simulate a specific directivity of a source and to optimize a corresponding room simulation. Our pilot study confirmed that this approach significantly improves the localization and sound quality of focused sources located inside the listening area.
