Place this clip right after the confusing statement in your edit, before your response shot. Follow it with a Ceeday Huh reaction for a second beat, or precede it with No No Wait Wait when the scene needs a quick backtrack first.
このサウンドについて
A spoken voice clip built around the phrase what do you mean, lasting just under seven seconds and delivered as a direct, questioning reaction. It gives a baffled, incredulous feeling, like someone has just heard something that does not add up and needs it explained again right away, slowly and clearly.
