Analog recording is a category of techniques used for the recording ofanalog signals. This enables later playback of the recordedanalog audio.

Analog audio recording began with mechanical systems such as thephonautograph andphonograph.^[1] Later, electronic techniques such aswire^[2] andtape recording^[3] were developed.

Analog recording methods store analog signals directly in or on the media. The signal may be stored as a physical texture on aphonograph record, or a fluctuation in thefield strength of amagnetic recording. Analog transmission methods use analog signals to distribute audio content.^[4] These are in contrast todigital audio where an analog signal issampled andquantized to produce adigital signal which is represented, stored and transmitted asdiscrete numbers.^[5]
