...modern computers are also clever. Today nothing is unaccountable if we know the formula and all variables. Audio is no mysterious. The complete sonic field would be calculatable. The only problem is the huge amount of variables. In principle, yet, we are able to calculate any wave front of the source and any of her reflections in the recording room. The Wave Field Synthesis provides the approach for handling the problem. The procedure can synthesize the complete spatial distribution of all wave fronts. In principle, also all reflections become to restore correct in time, level and direction, at least in the horizontal level of the loudspeaker rows. The really disturbing component always remained, as like at all other audio playback, the additional playback room acoustics, which deliver unwanted reflections.
However, at WFS we have a chance for avoiding that problem. All we need is including the playback room properties into the synthesis. By this way becomes possible, subtract the additional detours of single wave fronts in the playback room. Never conventional procedure will be able to that, because direct wave, first reflections and reverberation inseparably merge together in the transmitting channels. Thus, the playback room unavoidably remains the disturbing component in transmitting chain. No chance exists for true spatial audio by that way, thereby. And no chance exists for reproducing the source distance correctly in the traditional way.
