APPARATUS AND METHOD FOR REMOVING POP-UP NOISE IN A PORTABLE TERMINAL

摘要

PURPOSE: A pop up noise removing method in a portable terminal is provided to simply remove pop up noise of audio data which is rapidly reproduced such as key tone in the portable terminal. CONSTITUTION: A portable terminal senses interrupt which stops generating audio data(603). The portable terminal analyzes a sine wave curve about the audio data(605). The portable terminal finishes reproducing the audio data in case the termination of a sine wave curve collects in a reference value(607). The portable terminal compensates the audio data in case the termination of a sine wave curve does not collect in a reference value(611).
