The lightsaber is one of the most recognisable weapons from Star Wars, first seen in the 1977 film, and its humming, buzzing sound has become shorthand for sci-fi action online. Short loops like this one are made by creators who combine that familiar hum with modern glitch effects, giving an old movie sound a digital, corrupted feel for edits and memes. It is now used in fan videos, gaming clips and transitions, often alongside other short effects like Pew Pew, because the two sounds together instantly signal a playful, futuristic fight.
