In digital recording, digital audio and digital video is directly recorded to a storage device as a stream of discrete numbers, representing the changes in air pressure (sound) for audio and chroma and luminance values for video through time, thus making an abstract template for the original sound or moving image.
Analog audio (sound), or analog video made of a continuous wave must be converted into a stream of discrete numbers, representing the changes over time in air pressure for audio, and chroma and luminance values for video.
Beginning in the 1980s, music that was recorded, mixed and mastered digitally was often labelled using the SPARS code to describe which processes were analog and which were digital.

Famous quotes containing the word recording:
“Self-expression is not enough; experiment is not enough; the recording of special moments or cases is not enough. All of the arts have broken faith or lost connection with their origin and function. They have ceased to be concerned with the legitimate and permanent material of art.”
—Jane Heap (c. 1880–1964)
