Variable Density B&W Film for Monoaural Audio Only. No Movies, No Stories. Just Music.

Hi:

I like using variable-density analog B&W monoaural negative [no
positive and no "reversal"; just the negatives] film optical tracks
for audio. The audio characteristics of the film make my mouth-water.
Yes, for some wierd reason, the film's audio makes me hungry. To add
to the delicous audio quality , I would like to coat the film with bad-
butter* and tiny traces of bitminous and anthracite coals [as well the
smoke of those coals] before recording. After recording, I would like
to clean it in a dark environment and then develop the clean film.

*Here is the link which describes how my "bad butter" is made:

Why didn't they make an audio-only equivalent of this for music [i.e.
an optical audio tape]?

Why not replace *Analog Magnetic Audio Tapes* with *Analog Optical
Audio Tapes*??

Analog optical audio is used in films and sound better than analog
magnetic audio.

Magnetic tape contains static, humming, and other electromagnetic
disruptions whereas optical tape does not.

Optical tape is resistant to bar magnets whereas magnetic tape is not.

Analog optical audio records and plays in the same manner as film
does.

The difference for me, is, I'd like to use only the negative film and
no positive.

Any chance of my "Variable Density B&W Film for monoaural audio"
fanstasy turning real?

Audio signal, in the form of light changing its intensity in an
analogous manner to the sound, is shined onto a negative film. The
film is developed and playback is accomplished by shining light of a
constant intensity onto the developed film. As the light goes through
the film, the patterns on the film will change the intensity of the
light that is received by a photoelectric cell. The change in light
intensity results in a changing electric current which is sent into an
amplifier and then to a loudspeaker.

"The Tri Ergon Process uses a technology known as variable density,
which differed from a later process known as variable area. The Tri
Ergon process had a pattented flywheel mechanism on a sprocket which
prevented variations in film speed. This flywheel helped prevent
distortion of the audio. Tri Ergon relied on the use of a
photo-electric cell to transduce mechanicalsound vibrations into
electrical waveforms and then convert the electrical waveforms into
light waves. These light waves could then be optically recorded onto
the edge of the film through a photographic process. Another photo-
electric cell could then be used to tranduce the waveform on the film
into an electrical waveform during projection. This waveform could
then be amplified and played to the audience in the Theater. The Fox
Film Corporation acquired the rights to the Tri Ergon technology in
1927. "

The ERPI system, Fox-Case's Movietone, and De Forest's Phonofilm
usevariable-density recording film audio

I think mono and VD are better in quality. I don't like stereo or VA.
But then, "quality" is highly subjective. One's worst enemy can be
another's best friend.

Oh, and equally important. The source of light should be from the
flames of burning anthacite, ignited bitiminous coals, and bad butter
that has caught fire -- instead of electric lights.

I would like to record my favorite songs into an variable-density
analog B&W monoaural negative film track. I want to listen to these
songs after they are "filmed".
