The sound comes from Doors, the Roblox horror game released by LSPLASH in 2022, where players move through numbered doors while avoiding entities. Clips of its alert-style cues spread on TikTok and YouTube Shorts as players recorded tense runs and close escapes. Editors lifted the Progress Detected audio for memes outside gameplay, using it whenever someone advances, unlocks something, or gets caught mid-action. Its looping alarm became shorthand for unwanted advancement and rising danger, which is why it still appears in gaming edits and reaction videos.
