I know that in the 9th century, hydropowered organ that played interchangeable cylinders automatically was the basic device to produce and reproduce music mechanically until the second half of the nineteenth century. There was also an automatic flute player which was the first programmable machine. Bothhad the same inventor.
In the 14th century, a mechanical bell-ringer controlled by a rotating cylinder was invented.
All of the above could play stored music, but they could not play arbitrary sounds or record a live performance. They were also limited by the physical size of the medium. The first device that could mechanically record sound (but not play it back) was the phonautograph. The earliest known recordings of the human voice were phonautograms made on this machine. These include a dramatic reading in French of Shakespeare's Othello and music played on a guitar and trumpet. The recordings consisted of groups of wavy lines scratched by a stylus onto fragile paper that was blackened by the soot from an oil lamp.
The player piano, used a punched paper scroll that could store a long piece of music. This piano roll moved over the 'tracker bar', which first had 58 holes, was expanded to 65, and was then upgraded to 88 holes (one for each piano key). When a perforation passed over the hole, the note sounded. Piano rolls were the first stored music medium that could be mass-produced, although the hardware used to play them was too expensive for personal use. The fairground organ, developed in 1892, used a similar system of accordion-folded punched cardboard books.
