This version uses a barrel made of plaster of Paris. In this device, sound waves travelling through the air vibrated a parchment diaphragm which was linked to a bristle, and the bristle traced a line through a thin coating of soot on a sheet of paper wrapped around a rotating cylinder.
The sound vibrations were recorded as undulations or other irregularities in the traced line. Scott's phonautograph was intended purely for the visual study and analysis of the tracings.
Reproduction of the recorded sound was not possible with the original phonautograph. These recordings, made circainclude fragments of two French songs and a recitation in Italian.
On April 30,he deposited a sealed envelope containing a summary of his ideas with the French Academy of Sciencesa standard procedure used by scientists and inventors to establish priority of conception of unpublished ideas in the event of any later dispute.
This metal surface would then be given the same motion and speed as the original recording surface. A stylus linked to a diaphragm would be made to ride in the groove or on the ridge so that the stylus would be moved back and forth in accordance with the recorded vibrations.
It would transmit these vibrations to the connected diaphragm, and the diaphragm would transmit them to the air, reproducing the original sound.

The platen had a spiral groove on its surface, like the disk. Over this was placed a circular disk of paper; an electromagnet with the embossing point connected to an arm traveled over the disk; and any signals given through the magnets were embossed on the disk of paper.
If this disc was removed from the machine and put on a similar machine provided with a contact point, the embossed record would cause the signals to be repeated into another wire.
The ordinary speed of telegraphic signals is thirty-five to forty words a minute; but with this machine several hundred words were possible. This pulley was connected by a cord to a little paper toy representing a man sawing wood.
Hence, if one shouted: I reached the conclusion that if I could record the movements of the diaphragm properly, I could cause such records to reproduce the original movements imparted to the diaphragm by the voice, and thus succeed in recording and reproducing the human voice.
Over this was to be placed tinfoilwhich easily received and recorded the movements of the diaphragm.
I was in the habit of marking the price I would pay on each sketch.
