Audience reaction sounds like this amazed aaah come from live television and talent show recordings, where studio crowds are encouraged to respond loudly to reveals and performances. Clips of those gasps were later isolated and shared on soundboards and in video editors as a ready made reaction. Online, creators use the short crowd swell to borrow the feeling of a live show for edits that were filmed alone, turning reveals, tricks, and impressive moments into shared spectacles that need no explanation from a narrator or host.
