This film is available from courtesy of the Prelinger Archives. A transcript of the film can be found here.

The film is extremely technical, and details the mechanics of recording equipment through animation. While the equipment is contemporarily archaic, the principles applied might still be useful to filmmakers and audio recorders today. Interestingly, the end of the film projects waveforms of orchestral music to demonstrate what sound “looks” like—the feeling of which is reminiscent of Disney’s Fantasia (1940).
