Predating the Windows Ding...

[16mm filmstrip projectorfilter]: Anyone know where I can find an .mp3 or .wav or .avi of the ding for the slide advance of a 16mm filmstrip projector from the 1970s?

Here's a shot in the dark... Remember the 1970s and 1980s before VHS, when the teacher would get a slide set and reel from the bookmobile, dim the lights in the classroom and you would watch a filmstrip? I would really like to find (ideally) an isolated sample of the audible ding, as well as the sound of the 16mm projector. A bonus would be a small bit of the audo crackle of the voiceover so I can attempt to recreate the effect properly.

The Talented Mr. [Brian] Dewan recreated filmstrips in his stage show (and DVD) FOCUS. There are dings aplenty there, and you might even ask Brian about his filmstrip technique.

Aside from in my head? See if you cannot lay hands on Strangers with Candy DVDs; I recall filmstrips being used in at least one episode. I don't have audio now, but this might be it.

Here's a likely projector clip from Freesound.

There weren't any real standards for audible tones. If you're feeling kind to your audience, you can use a middle F above C played on a marimba or a tuning fork. If you're feeling not quite so kind, use a 350Hz sine wave. Less kind would be a 350Hz square wave. There's an applet here that will let you do that.

Note that a filmstrip projector made no sound other than the cooling fan.

Best answer: The wonderful A/V Geeks guy has filmstrips (and filmstrip projectors) in his collection. He also has a stock footage company on the side. Seems like a potentially helpful guy.

(Just to check, you want the sound of a filmstrip projector, not just a regular classroom 16mm film projector, right?)

Best answer: Yeah, filmstrip projectors didn't have the constant sprocket noise of a regular film projector, just the cooling fan. The ones at our schools (automatic advance, cassette tape) did make a very pleasant mechanical sound when advancing frames, though. Not as nice and chunky sounding as a slide projector, but still distinctive.

As for the audio, most audio editing programs will allow you to add some effects. I'd go with a sort of AM Radio preset for starters, and then add just a bit of LP crackle or random tape distortion, depending on the particular sound you're going for.

I seem to recall a tone around G just below A440 ... on a wooden xylophone.

See if you can find an open source sample of that.

Response by poster: So thusfar I think I've found something close - thanks to some great suggestions on search terms and sights to look through.
