phonautographs
- Scope note
- Early phonographic recording devices of the type invented by Léon Scott de Martinville in 1857, consisting of a horn or barrel focusing sound waves onto a membrane, and creating a visual analogue of soundwaves onto a lampblack-coated cylinder by means of a hog's hair bristle. It was the first sound recording device, but could not reproduce the recorded sound.
