摘要： An electronic device and method for cancelling wind noise from a sound signal input through a microphone is provided. An electronic device of the present disclosure includes an input device comprising input circuitry, an output device comprising output circuitry, and a processor configured to control the input device to acquire a first signal corresponding to external sound of the electronic device, to generate a second signal by delaying the first signal for a predetermined amount of time, to detect a third signal corresponding to the wind sound in the first signal using a predetermined detection method based on the first and second signals, and to control the output device to output a fourth signal obtained by controlling the third signal in the first signal.

摘要： An electronic device includes a communication module for supporting short-range wireless communication; a camera module for capturing a video; a display for displaying the video being captured; and a processor operatively connected to the communication module, camera module, and display. The processor may be configured to: connect with the external electronic device using the communication module; receive an audio signal from the external electronic device at the same time as the capturing of the video; confirm a target object among at least one object included in the video being captured; confirm first location information about the location at which the target object is displayed on the display; estimate, on the basis of the first location information, the actual location of the target object; generate second location information about the actual location; and process the audio signal on the basis of the generated second location information.

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.
