Thinking about it, if it was possible to find these two cylinders (red arrows)Bob Dillon wrote: ↑11 Jun 2019 18:07The first commercial cylinders in the late 1800's were made by the performer (s) playing into multiple cylinder recording machines at once and then repeating the process, so maybe they'd get a few hundred cylinders to sell at the end of a days work. Those would have been brown wax cylinders.
and replay them in sync one would be able to hear the artist in stereo!! A stereo-recording from a time when probably no-one was even thinking of stereo!
And if it was possible to find all the 13 cylinders from one take and relocate their positions, one would be able to hear the music in "super-13-channel-stereo"!
But leaving the "super-quatripple-13-channel-quattrophonic-dolby-surround-stereo" aside, i think these 13 horns do support my theory of being able to record louder with a bigger horn. Obviously the music is able to drive 13 diaphragms at once, so if a bigger horn was attached to a recording machine more of the energy the soundwaves have could be focused onto the diaphragm.
And if there were too many echoes with one big horn, one could place several smaller horns and connect them all to one recording head.
