    摘要： Disclosed is an apparatus and a method for enabling sound data having a three dimensional stereo sound effect to be reproduced in a mobile communication terminal. A three dimensional stereo sound reproducing apparatus for a mobile communication terminal comprises: a memory for storing sound data having a three dimensional stereo sound effect; a sound processing unit for reading the sound data from the memory when an incoming call is generated or when a user requests reproduction of the sound data and for decoding the sound data without distortion of the three dimensional stereo sound effect, thereby outputting the sound data as a type of an analog signal; and a speaker for amplifying the analog signal and outputting the amplified analog signal as a type of an audible sound. Therefore, it is possible to obtain an excellent three dimensional stereo sound effect and an excellent performance in reproducing original sound.

    摘要： An automatic gain controller and a method using the same are provided. The automatic gain controller and method analyze background noise by operating a microphone mounted in a mobile communication terminal and automatically control the gain of the signal part which is non-audible due to the background noise. Thus, a user may listen to music by using an earphone or a headphone connected to the mobile communication terminal in an environment with background noise. The method includes receiving an audio signal to be reproduced, receiving a background noise signal introduced through a microphone, controlling a gain of the audio signal by comparing the background noise signal and the audio signal and outputting the gain-controlled audio signal so that the user can listen to the gain-controlled audio signal.
