METHOD FOR PROCESSING AN AUDIO SIGNAL IN A MOBILE COMMUNICATION TERMINAL CAPABLE OF OFFERING COMFORT NOISE TO MAKE A COMFORTABLE CALLING ENVIRONMENT AND A DEVICE THEREOF

摘要

PURPOSE: A method for processing an audio signal in a mobile communication terminal and a device thereof are provided to divide a received audio signal into a voice signal and a noise signal and analyze the noise signal properties inputted through a microphone, thereby efficiently controlling the voice signal and the noise signal.;CONSTITUTION: A mobile communication terminal divides a received audio signal into a voice signal and a noise signal based on the energy level(205). The mobile communication terminal controls the frequency of the voice signal(209). The mobile communication terminal controls the energy level of the noise signal(211). The mobile communication terminal outputs a combined signal of a controlled voice signal and noise signal to a speaker(213,215).;COPYRIGHT KIPO 2012
