This short effect dates to July 19, 2015, when it was shared as a vocoder creation built with voice-changing software. Its name combines a city-night theme with that processed, electronic treatment, and its sub-second length made it easy to save, share, and reuse on soundboards. Over time, creators kept it in rotation not because it belongs to a famous film, game, or meme, but because short synthetic stings are endlessly reusable. It still appears in edits as a quick futuristic marker, valued for being instantly recognisable as a digital sound without carrying a specific story or character with it.
