Arrangement for 3-dimensional sound reproduction has inverse filter module for filtering sound input signal, time multiplex module that selects order filtering, and several loudspeakers

摘要

The arrangement has an inverse filter module (100) for filtering a sound input signal so that each listener (400) can have virtually the same sound source. A time multiplex module (200) selects the order of sound signals to be filtered by the inverse filter in a defined interval and several loudspeakers (300) output the signal selected by the time multiplexer as sound. An Independent claim is also included for a method of reproducing a sound input signal.
