Hello Stefan, good discussion. However: How many dry recorded audio tracks are there? There might be dozens... Therefore, you can't control things like space or data rate for streaming. I see the upper limit at 32. Nobody is able to separate more source positions in the real environment.

Hi Mark, what you describe, finally is the typically american solution: Printing money for solving the crisis or increase the number of channels for improve the spatial impression. We call the worn- out ways as commercial. But finally, more creative solutions will get the drop on. Regards H.

Hi David, you are not alone in your insigthes. Some single discrete reflections are the most important fact for estimation of source distance. There exist research from Helmut Wittek, who was proven, play the reverberation from four different directions is absolutely sufficient. We cannot use the

...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

Hi Augustine, the parallel wave front virtually originate from startimg point far away behind the loudspeaker array. In the same manner as the moon is following you, if you are walking across the street at nigth, the sound source follows your migration. Besides, a loudspeaker line cannot

...let us describe the main relations again. The surface of the wave front radiate from point source increase by pi*d quadrat. For double distance 4times larger surface results. 10 log (1/4) = - 6,02 dB. Cylinder wave surface doubled by double distance. 10 log( 1/2)= -3 dB. Plane wave surface
