    摘要： According to various embodiments disclosed in the present document, an electronic device may: acquire, through an application, a request for performing a call with another electronic device; in response to the acquisition of the request, identify a first sampling rate corresponding to a frequency band supported by the application so as to perform communication with another electronic device; acquire an audio signal through a microphone; identify a frequency band of the audio signal; determine a type of the audio signal on the basis of the frequency band; determine a second sampling rate corresponding to the audio signal on the basis of the type of the audio signal; determine a third sampling rate corresponding to a frequency band for performing a call with another electronic device, on the basis of the first sampling rate and the second sampling rate; determine a clock and a tuning parameter on the basis of the third sampling rate; and tune the audio signal on the basis of the clock and the tuning parameter. Various other embodiments identified through the specification are also possible.

    摘要： The present disclosure provides a method and system for voice enhancement. The method and system of the present disclosure may simultaneously perform signal processing of two paths on an input signal. The first path signal processing includes receiving an audio source input and performing dynamic loudness balancing on the audio source input based on a first gain control parameter. The second path signal processing includes: performing voice detection on the audio source input and calculating a detection confidence; and calculating a second gain control parameter based on the detection confidence. The first path signal processing and the second path signal processing may be synchronous or asynchronous. The method of the present disclosure also includes updating the first gain control parameter with the second gain control parameter calculated by a second processing path, and performing the first path signal processing based on the updated first gain control parameter.
