Using the in-house Finite Difference Time-Domain (FDTD) software it is possible to make simulations of sound propagation in rooms with complex geometries and with different absorbing boundaries, this makes for an accurate test bed for all sorts of reproduction techniques in different rooms. Shown here is a wave field synthesis (WFS) system modelled in a large hall. This allows us to see how the room affects the accuracy of the WFS reproduction.

The four different views shown on this video are the front, top and side views of the room and the top corner shows the room impulse response as measured by a receiver in the room (marked by a yellow square)
