Re: Audio recording: some interesting research tid-bits
After reading Garmt's messages and the replies, I had to do
my own research, and here are some interesting tidbits:
- Besides the commercially released brown wax cylinders, the UCSB
collection also contains a small series of home recordings. These
cylinders were made from wax "blanks," which Edison claimed
could be reused up to one hundred times by literally shaving off the old
grooves. In this way, brown wax blanks could perhaps be considered an
early rewritable medium, akin to a CD-RW today. For these home
recordings, discerning identification information as well as playback
speed is often impossible. Yet hearing them can be a fascinating, even
otherworldly experience: a crying baby who cannot be pacified, say, or a
drunken caterwauler flailing through a song, their identities forever
lost to time.

Edison stopped making cylinder record
players in 1929 but recording on reusable wax cylinders remained common
in dictating machines until the end of the Second World War. The Museum
has 31 such machines made by Edison and Dictaphone Corp (740325).

Shortly after
Thomas
Edison invented the
phonograph,
the first device for recording sound, in
1877, he thought
that the main use for the new device would be for recording speech in
business settings. (Given the low
audio fidelity of earliest versions of the phonograph, thinking that
recording speech would be more important than recording
music may not have
been as absurd an assumption as it may seem in retrospect.) Some early
phonographs were indeed used this way, but this did not become common
until the mass production of reusable
wax cylinders in the
late 1880s. The
differentiation of office dictation devices from other early phonographs
(which commonly had attachments for making one's own recordings) was
gradual.

Alexander Graham Bell took this invention a step further by replacing
the foil-covered cylinder with one coated with wax. The needle cut a
pattern that varied in depth onto the wax surface. For recording, Bell
relied on a very sharp stylus and firm membrane. During playback, he
switched to a dull stylus and a looser membrane so as not to destroy the
original impressions. To reuse the cylinder, the wax could be shaved and
smoothed. For the first time, sound recording could be accomplished on
removable and reusable media. The process was further improved with the
addition of an electric motor to replace the hand crank, so that
recording and playback took place at uniform speeds. Recorded cylinders
were then metal-plated to create a mould so that a number of copies of
the original could be produced.

Optical carriers
The compact disc is probably the greatest innovation in the
reproduction of sound since Edison's wax cylinders.

I particularly like this one (below)..it seems that
Edison perfected the tin recording, then moved on to the light bulb, and
Alexander Graham Bell made the change to wax ..and here's the good
part...*****using his winnings from the Volta Prize of $10,000 from the
French government for his invention of the telephone...***
So thanks to the French government, we now have a recording of Jules
Verne!!!
So this has become a French ($10,000 prize)/American (Edison)/Canadian
(Bell)/ and now Dutch (Garmt/Appel)/ and German (Krauth
) collaboration.....Hurray for the International community!!!
- Edison took his new invention to the offices of Scientific
American in New York City and showed it to staff there. As the
December 22, 1877, issue reported, "Mr. Thomas A. Edison recently
came into this office, placed a little machine on our desk, turned a
crank, and the machine inquired as to our health, asked how we liked the
phonograph, informed us that it was very well, and bid us a cordial good
night." Interest was great, and the invention was reported in
several New York newspapers, and later in other American newspapers and
magazines.
- ............
- The Edison Speaking Phonograph Company was established on January 24,
1878, to exploit the new machine by exhibiting it. Edison received
$10,000 for the manufacturing and sales rights and 20% of the profits. As
a novelty, the machine was an instant success, but was difficult to
operate except by experts, and the tin foil would last for only a few
playings.
- Eventually, the novelty of the invention wore off for the public, and
Edison did no further work on the phonograph for a while, concentrating
instead on inventing the incadescent light bulb
- In the void left by Edison, others moved forward to improve the
phonograph. In 1880, Alexander Graham Bell won the Volta Prize of $10,000
from the French government for his invention of the telephone. Bell used
his winnings to set up a laboratory to further electrical and acoustical
research, working with his cousin Chichester A. Bell, a chemical
engineer, and Charles Sumner Tainter, a scientist and instrument maker.
They made some improvements on Edison's invention, chiefly by using wax
in the place of tin foil and a floating stylus instead of a rigid needle
which would incise, rather than indent, the cylinder. A patent was
awarded to C. Bell and Tainter on May 4, 1886. The machine was exhibited
to the public as the graphophone. Bell and Tainter had representatives
approach Edison to discuss a possible collaboration on the machine, but
Edison refused and determined to improve the phonograph himself. At this
point, he had succeeded in making the incandescent lamp and could now
resume his work on the phonograph. His initial work, though, closely
followed the improvements made by Bell and Tainter, especially in its use
of wax cylinders, and was called the New Phonograph.

Please note the mention of "2 minute recording
time"..so if Garmt found 5 cylinders = 10 mins, and it was an
interview, we may have 5 or more minutes of Verne's voice (i.e. 2
participants, 5 mins each!)
- In 1894, Edison declared bankruptcy for the North American Phonograph
Company, a move that enabled him to buy back the rights to his invention.
It took two years for the bankruptcy affairs to be settled before Edison
could move ahead with marketing his invention. The Edison Spring Motor
Phonograph appeared in 1895, even though technically Edison was not
allowed to sell phonographs at this time because of the bankruptcy
agreement. In January 1896, he started the National Phonograph Company
which would manufacture phonographs for home entertainment use. Within
three years, branches of the company were located in Europe. Under the
aegis of the company, he announced the Spring Motor Phonograph in 1896,
followed by the Edison Home Phonograph, and he began the commercial issue
of cylinders under the new company's label. A year later, the Edison
Standard Phonograph was manufactured, and then exhibited in the press in
1898. This was the first phonograph to carry the Edison trademark design.
Prices for the phonographs had significantly diminished from its early
days of $150 (in 1891) down to $20 for the Standard model and $7.50 for a
model known as the Gem, introduced in 1899.
- Standard-sized cylinders, which tended to be 4.25" long and
2.1875" in diameter, were 50 cents each and typically played at 120
r.p.m. A variety of selections were featured on the cylinders, including
marches, sentimental ballads, coon songs, hymns, comic monologues and
descriptive specialities, which offered sound reenactments of events.
- The early cylinders had two significant problems. The first was the
short length of the cylinders, only 2 minutes. This necessarily narrowed
the field of what could be recorded. The second problem was that no mass
method of duplicating cylinders existed. Most often, performers had to
repeat their performances when recording in order to amass a quantity of
cylinders. This was not only time-consuming, but costly.
- The Edison Concert Phonograph, which had a louder sound and a larger
cylinder measuring 4.25" long and 5" in diameter, was
introduced in 1899, retailing for $125 and the large cylinders for $4.
The Concert Phonograph did not sell well, and prices for it and its
cylinders were dramatically reduced. Their production ceased in 1912.
- .........
- A new business phonograph was introduced in 1905. Similar to a
standard phonograph, it had alterations to the reproducer and mandrel.
The early machines were difficult to use, and their fragility made them
prone to failure. Even though improvements were made to the machine over
the years, they still cost more than the popular, inexpensive Dictaphones
put out by Columbia. Electrical motors and controls were later added to
the Edison business machine, which improved their performance. (Some
Edison phonographs made before 1895 also had electric motors, until they
were replaced by spring motors.)
- At this point, the Edison business phonograph became a dictating
system. Three machines were used: the executive dictating machine, the
secretarial machine for transcribing, and a shaving machine used to
recycle used cylinders. This system can be seen in the Edison advertising
film,
The Stenographer's Friend, filmed in 1910.

Dear all,
I have received many reactions to my message about the audio recording of
the interview with Jules Verne. I'm sorry that I don't have time to reply
to each of you individually right now (I'm in the middle of a
renovation).
Some fair points have been made by various people: don't mess around with
the cylinders yourself, as they are very fragile; keep them safe, because
you never know what some people may do when they hear about this; and
keep it quiet for the moment. These are things I hadn't considered in my
enthusiasm.
I have made a couple of phonecalls, and it turns out there's a museum
that maintains an archive of old recordings, and also has a lot of
experience with digitizing vinyl records, wax cylinders, etc. Rina Appel
and I have been invited to come to the museum on Friday, so that's what
we'll do, rather than working on the cylinders ourselves. The technician
I talked with couldn't promise that the entire interview could be
transferred in one evening, but most probably we will be able to make a
short sample, which I'll post as promised.
Once the operation is underway, we'll see how we go about going public
with it. For the time being, the cylinders will be stored in a safe at a
bank.
Cheers,
Garmt.
