摘要： An electronic device and method are disclosed. The electronic device includes an internal microphone, a communication module, and at least one processor. The processor implements the method, including: receiving, through the communication module, a first audio signal input through an external microphone included in an external electronic device communicatively connected to the electronic device, activating the internal microphone in response to detecting a device switch event switching from the external microphone to the internal microphone while receiving the first audio signal, receiving a second audio signal input through the internal microphone, synchronizing and mixing the first audio signal and the second audio signal during a designated first time period, and deactivating the external microphone upon detecting lapse of the designated first time period.

摘要： An electronic device is provided. The electronic device includes a camera, a plurality of microphones, at least one processor electrically coupled with the camera and the plurality of microphones. The at least one processor may acquire a video signal, based on a designated zoom level via the camera, acquire a plurality of audio signals respectively via the plurality of microphones while acquiring the video signal, identify a first signal characteristic of a first audio signal acquired via a first microphone and a second signal characteristic of a second audio signal acquired via a second microphone among the plurality of microphones, derive a control parameter for signal processing for the first audio signal and the second audio signal, based on the designated zoom level, the first signal characteristic, and the second signal characteristic, and perform audio signal processing including beamforming using the first audio signal and the second audio signal, based on the derived control parameter. Various other embodiments are also possible.
