80-Year-Old Edison Recording Resurrected 133

embolalia writes "An 80-year-old recording of a live radio broadcast featuring Thomas Edison has been uncovered and reconstituted. The recording was done on an obscure technology called a pallophotophone — Greek for 'shaking light sound' — that uses optical film to reproduce sound. The archivists who uncovered the canisters tucked away on a bottom shelf in a museum in Schenectady, New York (the city where Edison's General Electric was founded), did not have any machine to replay the films. Two GE engineers — working nights and weekends for two years — were able to construct a machine to replay the old tapes, recorded only two years before Edison's death." There's a video at the link, which may or may not contain some of the resurrected recording, but we couldn't get it to play from the Times Union site.

      Law firm representing NBC has filed suit alleging their client's copyrights have been violated for unauthorized rebroadcasting of the film content. "The audio programs recorded on those films are wholly owned intellectual properties belonging to our client, and their unauthorized rebroadcasting over the web is a willful theft of our client's intellectual properties. We fully intend to pursue this matter for the maximum payou... punitive damage under our law... ahm, the law."

      • But Edison is dead. His copyright should have expired with him. Or 14 years - whichever came first.

        And I'm not sure what the big deal is about optical recording on film? That's how most films of the 1920s, 30s, and 40s record their sound and is commonly understood. Maybe it took the engineers two years to decode the precise format.

    This is neither the only recording of the broadcast, nor the best. A recording of the broadcast made by Edison's own technicians on his then-state-of-the-art 30 RPM radio transcription system was restored by Professor Mike Biel and released by Mark 56 Records three decades ago.

      Even so, they mentioned seven canisters. Assuming 1000 ft canisters at what would be 24 FPS, we get approximately 77 minutes of audio? I don't know how long the broadcast was, but if that is longer than the broacast, perhaps it has additional material.

      If not, there still could exist other audio reels in this format someplace or other, which could benefit from the machine designed to recover the audio.

    In some ways, it is interesting to think that it is technically easier to recover data from this sort of recording (and likewise, other analog systems like magnetic reel-to-reel tape and records) long after the means to recover the data are lost compared to more modern, computerized formats. I sometimes worry about the 'lasting-ness' of all my JPEG photography compared to my film negatives through this same issue.
    • It's probably true that analog formats are more lasting if they're forgotten about for a while, as in this case, because they degrade relatively gracefully.

      Digital media will be saved by digital virtues, principally the ease of making many perfect copies. You back up your JPEGs, right? Robust digital data is data for which there are many copies.

      I used to live down the street from John Schneider (one of the engineers who worked on this). He's actually a multi-millionaire who started his own company a few years back and it's pretty cool that he's still getting his hands dirty with things like this.
      Here's a bio.. http://www.spoke.com/info/pOzZMi/JohnSchneiter

      Although he's a really smart guy, he's not really super computer savvy - as is common for a lot of MechEs so it makes sense that he would try to solve this problem using hardware since that's what he knows. Naturally myself (and likely most software guys) would get a high resolution scanner out and write some code to "playback" the stored audio. I've seen similar applications for playing old records that don't require actually touching the record with a needle. Regardless, you really only need to play it once and digitize the audio so the concern of multiple playbacks ruining the film isn't that big of a concern.

      All in all a really cool hack!

    • Exactly. It's optical. If it was magnetic you'd probably need some specialized head to read it, but since it's optical you can just use a scanner then go straight to processing it with software. Seems like the most cost effective and easiest solution. Not as cool as building a machine, but what's the point?

      The machine they built winds the film onto reels, and then plays it back in front of a light source, that's shining onto some sort of photocell that re-creates the sound. The sound is clearly put into a digital computer feed (note the obvious sound wave on the monitors in the background of the video.) Likely, each reel was only run through once, or maybe twice, and converted into a useful, digital version.

      In other words, they scanned the film and then decoded it.

    It is during instances and moments like these that we should be reminded of exactly how bad it is to protect content and patent data processing methods. These are the surest ways for us to lose the historical data we are creating today. Already, losses of great works have been lost due to lack of republication because copyright has not expired before the last copies were lost forever. If it were not for a few brave individuals, Disney's "Song of the South" would be lost forever today as they will never EVER publish it again and it is not available for sale anywhere.

    And more and more, we are seeing technologies phasing out... floppy disks... anyone got an 8" floppy drive laying around? What about 5 1/4" No? I still have a few USB 3.5" floppy drives but that was only to make a floppy disk RAID for fun. We might find some paper tape somewhere in an archive out there in a dark closet, but will we find a reader for it?
