5. Calculations of SPL and STI taking into account early reflections.

Array Builder is a loudspeaker array simulator performing prediction of the sound field parameters both in open spaces and closed rooms. The simulator enables easy and intuitive control over the shape of the array to optimize its acoustic performance. The loudspeaker model uses the Virtual Waveguide model of drivers calculating a complex amplitude in the output aperture of the device which is unique for the engineering simulators.
