Über diesen Sound
The clip is a single drawn-out human voice blurting 'dahhh' for just over two and a half seconds, stretched like a brain that has stopped working mid-thought. It feels gleefully dumb and awkward, the sound of someone caught out, confused, or pretending they understood something they clearly did not.
