===Sound===
The lightsaber [[sound effect]] was developed by sound designer [[Ben Burtt]] as a combination of the hum of idling [[Movie projector#Automation and the rise of the multiplex|interlock motors]] in aged movie projectors and interference caused by a television set on a shieldless [[microphone]]. Burtt discovered the latter accidentally as he was looking for a buzzing, sparking sound to add to the projector-motor hum.<ref name="Burttlaserdisc">{{citation|author=Burtt, Benn|author-link=Ben Burtt|title=[[List of changes in Star Wars re-releases#Laserdisc editions|Star Wars Trilogy: The Definitive Collection]] |publisher=[[Lucasfilm]] |quote=...the microphone passed right behind the picture tube and as it did, this particular microphone produced an unusual hum. It picked up a transmission from the television set and a signal was induced into its sound reproducing mechanism, and that was a great buzz, actually. So I took that buzz and recorded it with the projector motor sound and that fifty-fifty kind of combination of those two sounds became the basic Lightsaber tone."|year=1993}}</ref>

The pitch changes of lightsaber movement were produced by playing the basic lightsaber tone on a loudspeaker and recording it on a moving microphone, generating [[Doppler shift]] to mimic a moving sound source.<ref>{{cite news|title=Why We Still Love Star Wars: Lightsaber 101|work=[[Parade magazine]]|date=December 3, 2017|pages=9|quote=The lightsaber wooshing sounds are created by waving a microphone in front of a speaker playing humming and buzzing noises.}}</ref>
