Sound recording is the storage of sound so that a person can hear the same sound more than once. It is a process wherein sound waves are captured by a machine. The machine converts the waves into electrical signals or binary data, that are then stored on recording media (such as CDs or computer hard drives). The sound can then be played back by reversing the process.
The first machines for recording sound were mechanical, not electrical. The phonograph was invented by Thomas Alva Edison in 1877. Phonographs have a spinning cylinder covered in a soft material such as tin foil, lead, wax, or amberol. Sound waves shake a small needle so that its motion carries the waves.
