Variable Density B&W Film for monoaural audio
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. 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. http://www.mtsu.edu/~smpte/twenties.html "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 use variable-density recording film audio *Here is the link which describes how my "bad butter" is made: http://groups.google.com/group/uk.fo...111377c?hl=en& Regards, Radium |

I think you are an exception to Usenet Property #1: "The answer to the question 'Am I the only one?' is always 'No'": there is somewhere someone with the same interest to talk to. You most likely are [or are about to become] the leading authority on recording sound onto butter smeared film. Whether this is possible, how it is done, and what are the results -- the world can only await the report of your experimental results. -- Nicholas O.

Call Trackwise or Chicago Optical, send them a tape and some money and they'll send you back some film with a VD track. It might be a substantial amount of money, though. I can do 16mm VD tracks with an Auricon galvo box here, but I'd charge more than a few hundred bucks to get the thing out of the closet and make sure it is up to factory specs first. --scott -- "C'est un Nagra.
