METHOD FOR PROCESSING AUDIO SIGNAL AND WIRELESS COMMUNICATION DEVICE

摘要

The present invention relates to a method for enhancing call voice quality by reducing noise in a receiving voice signal during a phone call and a wireless communication terminal for the same. According to the present invention, a method for processing a voice signal in a wireless communication terminal includes: a step of receiving a voice signal from an external device through a wireless communication unit; a step of decoding the received voice signal; a step of reducing noise in the decoded voice signal; a step of changing the dynamic range of each frequency band using pre-stored audiometry test result; a step of changing the voice signal from which noise is reduced using the changed dynamic range of each frequency band; and a step of converting the changed voice signal into an analog signal and outputting the analog signal through a speaker.
