An electronic device may include a camera and a processor operatively connected to the camera, wherein the processor may be configured to: acquire video data through the camera; receive first audio data through a first audio input device; perform a connection configuration of a second audio input device as the device receiving audio data is switched from the first audio input device to the second audio input device; calculate a gap time on the basis of a time consumed for completing the connection configuration of the second audio input device; generate silent data on the basis of the calculated gap time; receive second audio data from the second audio input device; and synchronize the video data, the first audio data, the silent data, and the second audio data. Various other embodiments are possible.
