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.

Electronic device with audio zoom and operating method thereof

A method of fabricating a semiconductor memory device includes forming a hard mask pattern using a damascene method on a lower mold layer stacked on a substrate and etching the lower mold layer using the hard mask pattern as an etch mask to define a protrusion under the hard mask pattern. A support pattern is formed on a top surface of the etched lower mold layer, the top surface of the etched lower mold layer being located at a lower level than a top surface of the protrusion. A lower electrode supported by the support pattern is formed.
