Electronic device and method for outputting sound

Abstract

Electronic devices and methods of use include a plurality of microphones, a speaker, an audio module, and a processor electrically coupled to the plurality of microphones, the speaker, and the audio module. The processor may be configured to control the audio module to separate each of input signals of ambient sounds input respectively through the plurality of microphones into a plurality of frequency bands by frequency conversion, control the audio module to obtain a gain value for each of the plurality of frequency bands based on an inter-channel phase variance for the plurality of frequency bands, control the audio module to filter a first frequency band signal with a directionality based on the gain value for each of the plurality of frequency bands, and control the speaker to output an output signal processed based on the first frequency band signal.
