The IDK sound effect is a short voice clip of someone saying I don't know, often used as a shrug reaction in memes, edits and funny chat replies.

This is a brief spoken clip of the phrase I don't know, delivered in a flat, unbothered tone that makes the uncertainty feel intentional. The voice is casual and slightly drawn out, turning a simple admission into a comedic shrug. At just over two seconds it lands quickly without needing any setup or context. Viewers instantly read it as confusion, indifference, or playful avoidance, which is why it works so well as a reaction. It punctures awkward questions and clueless moments, letting the sound do the shrugging for the person on screen.

The phrase I don't know has been shortened online to IDK for decades in texts and chats, and this audio version turns that shorthand into a spoken reaction.
