Re: [ARSCLIST] Early Stereo 1881 and 1931 (Was - Dynadoodoo

[Robert J Hodge <rjhodge@xxxxxxx>]

The Columbia Multiplex Grand Graphophone of 1900 used a single wax
cylinder which contained three tracks designed to be played back
simultaneously with three reproducers through three horns.
If the three tracks were recorded with three horns and 3 recorders, then
this could easily be one of the first stereophonic machines.

Unfortunately only two of the machines were built. According to Howard
Hazelcorn's book "Columbia Phonograph Companion", page 101, one of the
machines and the cylinders may survive in Iran as the Shah had one built
for him - and 30 barrels of the special cylinders.

The first commercial stereo that I'm familiar with was done by Cook
Labs. The LP was divided in half for the left and right tracks. The tone
arm looked like a large tuning fork (each cartridge picked up one
track). When it was right it was great. If one of the heads was off one
groove it was horrible requiring an adjustment to a small adjusting
screw which would move the heads either closer together or further
apart.

I had read about the 1881 system,but have never actually heard anything
about it.

Oh,BTW,your file won't play on a Mac.

I would assume the Bell Labs stuff,is from those 1979-80 Lps,that
nearly every classical Lp collector owns.

Don't forget that Edison supposedly had some expensive,and cumbersome
system,that involved three channel/three horn playback.Perhaps someone
could give me more detail.

One file, Bell Labs Keller, has two brief programmes on BBC Radio 3 c.

about the Bell Labs experiments in the early 30s and includes a an
extract

about 
the Black Box. (74MB)

The other file, 1881 Stereo, is a brief Radio 3 broadcast in 1981 about
the 
1881 stereo transmissions from the Paris Opera, and demonstrates the
sound 
characteristic using reconstructed microphones on the stage of Covent 
Garden. (27MB)

The files are in Flac format.  They can be played directly in Winamp,
VLC 
Media Player, Super (c) etc.  They can be converted to Wave using Flac
Front 
End, Goldwave etc.

The files are taken from a Scotch Metafine tape with Dolby C.  The
original 
recordings were made by me but the tape I used may be a dubbing. 
However, 
the sound quality is  acceptable.
