This short clip comes from user uploaded soundboards with no documented original film, show or song source, so its history is mainly online rather than in a studio release. The phrase spread as a reusable reaction because it fits almost any baffling moment without needing context about who is speaking. Short deadpan voice lines like this travel well on short form video and in group chats, where a one second shrug can replace a typed reply. It remains in use because the confusion is universal and instantly readable.
关于此声音
Short voice clip of someone flatly saying idk it is that, used as a shrug reaction for confused moments, awkward questions and clueless replies online.
Idk it is that is a one second voice line delivered in a flat, unsure tone, as if the speaker is giving up halfway through an explanation. The wording is vague on purpose, which is exactly why it lands as a joke. It does not answer anything, it just signals confusion, indifference and a shrug in audio form. Creators drop it right after a strange claim or a question nobody can explain, and the deadpan delivery makes the non answer feel funnier than a real reply would.
