Abstract: An electronic device and method are disclosed. The electronic device includes a first microphone, a second microphone, a memory; and a processor. The processor implements the method, including: determining whether a voice is detected in a first sound signal detected by the first microphone; determine whether a present recording period is a voice period or a silent period based on the determination, when the present period is the silent period, receive a second sound signal via the second microphone and analyze a noise signal included therein, remove noise signals from one of the first and second sound signals, based on characteristics of the voice period or the analyzed noise signal, and combine the first and second sound signal into an output signal and transmit the output signal to an external device.

Abstract: An electronic device includes a memory, a communication interface capable of performing communication, and a processor electrically connected to the memory and the communication interface. The processor is configured to extract a first audio signal to be output through a speaker, based on audio data received from an external electronic device and/or stored in the memory, to generate a second audio signal obtained by removing the first audio signal from the audio data, and to generate a haptic signal for outputting a haptic effect, based on the second audio signal.
