Earliest known device for recording sound; patented by Édouard-Léon Scott de Martinville in 1857 The **phonautograph** is the earliest known device for recording [sound](/wiki/Sound "Sound"). Previously, tracings had been obtained of the sound-producing vibratory motions of [tuning forks](/wiki/Tuning_forks "Tuning forks") and other objects by physical contact with them, but not of actual sound waves as they [propagated](/ wiki/Wave_propagation "Wave propagation") through air or other [media](/wiki/Transmission_medium "Transmission medium").
