Autotuned baby laughs became a familiar meme sound as short-form creators began pitching everyday giggles into musical jokes for TikTok, Reels and YouTube Shorts. The effect works because it keeps the laugh recognisable while making it sound intentionally produced, which fits reaction edits, cute animal-style compilations and lighthearted prank videos. It has stayed popular because it is short, instantly understandable without context and easy to drop over almost any wholesome or absurd moment. The related baby laughing meme captures a similar playful energy for creators who want a more natural version.
