20090299740 | METHOD OF PROCESSING AUDIO SIGNALS FOR IMPROVING THE QUALITY OF OUTPUT AUDIO SIGNAL WHICH IS TRANSFERRED TO SUBSCRIBER'S TERMINAL OVER NETWORK AND AUDIO SIGNAL PRE-PROCESSING APPARATUS OF ENABLING THE METHOD - A method of pre-processing an audio signal transmitted to a user terminal via a communication network and an apparatus using the method are provided. The method of pre-processing the audio signal may prevent deterioration of a sound quality of the audio signal transmitted to the user terminal by pre-processing the audio signal, and by enabling a codec module, encoding the audio signal, to determine the audio signal as a speech signal. Also, the method of pre-processing the audio signal may improve a probability that the codec module may determine a corresponding audio signal as a speech when the audio signal is transmitted via the communication network by pre-processing the audio signal using a speech codec. | 12-03-2009 |
