The multiply-accumulate block operates on a time division multiplexed basis, so that multiple signal paths can be processed within one period of the sample clock.

Abstract: Virtual sound room rendering is most realistic when the listener has themselves been the subject of the binaural room impulse response measurements, and most pleasing when the sound room involved has a high acoustic fidelity. Where the listener has no access to good sound rooms non-personalised high fidelity sound rooms are modified using information from a listener's personalised binaural impulse response data to improve the realism of such rooms. Where sound rooms are available, information from higher fidelity non-personalised sound rooms are used to improve the sound quality of the listener's personalised room data. Alternatively either personalised or non-personalised rooms can be improved through modification of their reverberation characteristics according to the listener's taste.
