Abstract: 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.

Abstract: A method and an electronic device for outputting an audio signal in the electronic device is provided. The electronic device includes a first speaker, a second speaker, and an audio processor that creates, from an audio signal, a first frequency audio signal corresponding to a first frequency band by using a low pass filter, synthesizes the created first frequency audio signal and the audio signal to create a synthetic audio signal, creates, from the synthetic audio signal, a second frequency audio signal corresponding to a second frequency band by using a high pass filter, outputs the created second frequency audio signal through the first speaker, and outputs the created synthetic audio signal through the second speaker.
