A one-dimensional two-channels stereophonic standard

Posted 7th February 2017 at 02:47 PM by Grasso789
Updated Yesterday at 03:58 PM by Grasso789 (Cuts, new findings and finally small fixes)

Recently it has been archieved to capture, store, propagate and play back audio with the full human hearing frequency range (16 to 16000 Hz) and contrast (7 Bel). Still, if a big sound source or several sound sources at once are the matter of content, such playback sounds artificial, because all is emitted from one small single acoustic source. In order to hear, what is going on, we use both ears simultaniously, turn our head in different directions and will detect the electro-acoustic device.

While an indetectable electro-acoustic reproduction incorporated myriads of tiny microphones, storage and transmission channels and a huge sphere covered by loudspeakers, we can help imagination at least a little bit by introducing sonic differences between left and rite. We also want this stereo, after Greek stereos shape, to integrate thoroly and easily with already existing mono electro-acoustics. Therefore we may at most double transmission and storage channels, for example by...

Levels- and spectra-pathing symmetrical arrays of monopoles

This is about spectra-pathing ("multi-way") loudspeakers made of several monopoles, in explanation omni-directional sound sources, but I really mean direct radiators as opposed to horns, which are more uni-directional. I think about home, rehersal and club loudspeakers, not stadium ones. While spectra-pathing enables large power at wide bandwidth, seams between paths are usually audible, altho that could have been avoided rite from the start, at least technically. But instead of fixing problems at source, one has relentlessly used power to paint over them.

Computers can cover up phase distortion, which has been introduced by common spectra-pathing, and improve beamwidth. But the natural solution is a symmetrical arrangement of lopass drivers embracing one hipass driver, an arrangement commonly referred to as D'Appolito arrangement, combined with a cross-over of first order.

When Germans started to loose ground in World War II, widerange drivers...
