Digital

Definition

In digital recording audio signals picked up by the microphone are converted into a stream of discrete numbers representing the sound wave, then recorded to a storage device.

To play back a digital sound recording, the numbers are retrieved and converted back into their original analogue waveforms so that they can be heard through a loudspeaker.

As the audio is stored as a series of numbers it is possible to make multiple copies without degrading the original file.

If some of the numbers become corrupted you may hear a glitch on playback.
