13 Facts About Sound recording

Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc.

Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record.

Sound recording called it the Phonautograph and patented it on March 25, 1857.
