'''Analog recording''' is a category of techniques used for the recording of [[analog signal]]s. This enables later playback of the recorded '''analog audio'''.

Analog audio recording began with mechanical systems such as the [[phonautograph]] and [[phonograph]].<ref>{{cite web |url=https://www.npr.org/templates/story/story.php?storyId=89380697 |title=1860 'Phonautograph' Is Earliest Known Recording |last=Flatow |first=Ira |date=April 4, 2008 |website=[[NPR]] |publisher=npr |access-date=January 25, 2023}}</ref> Later, electronic techniques such as [[wire recording|wire]]<ref>{{cite journal |last1=Morton |first1=David |date=April 1998 |title=Armour Research Foundation and the Wire Recorder: How Academic Entrepreneurs Fail |url=https://www.jstor.org/stable/3107045 |journal=Technology and Culture |volume=39 |issue=2 |pages=213–244 |doi=10.2307/3107045 |jstor=3107045 |s2cid=112428198 |access-date=January 25, 2023|url-access=subscription }}</ref> and [[tape recorder|tape recording]]<ref>{{cite web |url=http://history.sandiego.edu/gen/recording/notes.html#tape |title=Recording Technology History |last=Schoenherr |first=Steven E. |date=July 6, 2005 |website=Recording Technology History |publisher=University of San Diego |archive-url=https://web.archive.org/web/20190216131304/http://history.sandiego.edu/gen/recording/notes.html#tape |archive-date=February 16, 2019 |access-date=January 25, 2023}}</ref> were developed.

Analog recording methods store analog signals directly in or on the media. The signal may be stored as a physical texture on a [[phonograph record]], or a fluctuation in the [[field strength]] of a [[magnetic recording]]. Analog transmission methods use analog signals to distribute audio content.<ref>{{cite web |url=http://artsites.ucsc.edu/EMS/music/tech_background/TE-19/teces_19.html |title=ANALOG RECORDING OF SOUND |last=Elsea |first=Peter |date=1996 |website=UCSC Electronic Media Studios |publisher=UC Santa Cruz |access-date=January 25, 2023}}</ref> These are in contrast to [[digital audio]] where an analog signal is [[Sampling (signal processing)|sampled]] and [[Quantization (signal processing)|quantized]] to produce a [[Digital signal (signal processing)|digital signal]] which is represented, stored and transmitted as [[discrete number]]s.<ref>{{cite web |url=http://artsites.ucsc.edu/EMS/music/tech_background/TE-16/teces_16.html |title=Basics of Digital Recording |last=Elsea |first=Peter |date=1996 |website=UCSC Electronic Media Studios |publisher=UC Santa Cruz |access-date=January 25, 2023}}</ref>
