Edison first tried recording sound on a wax-impregnated paper tape, with the idea of creating a "telephone repeater" analogous to the telegraph repeater he had been working on.
Numerous applications for the phonograph were envisioned, but although it enjoyed a brief vogue as a startling novelty at public demonstrations, the tinfoil phonograph proved too crude to be put to any practical use.Along with a tuning fork tone and unintelligible snippets recorded as early as 1857, these are the earliest known recordings of sound. Unlike the phonautograph, it was capable of both recording and reproducing sound.Despite the similarity of name, there is no documentary evidence that Edison's phonograph was based on Scott's phonautograph.or 45 rpm); their reproductive quality, or level of fidelity (high-fidelity, orthophonic, full-range, etc.); and the number of audio channels (mono, stereo, quad, etc.).Vinyl records may be scratched or warped if stored incorrectly but if they are not exposed to high heat, carelessly handled or broken, a vinyl record has the potential to last for centuries.From the 1990s to the 2010s, records continued to be manufactured and sold on a much smaller scale, and were especially used by disc jockeys (DJs) and released by artists in mostly dance music genres, and listened to by a niche market of audiophiles. As of 2017, 48 record pressing facilities remain worldwide, 18 in the United States and 30 in other countries.
