ABSTRACT:
A method and apparatus are provided for converting an analog audio signal into digital data. A signal with small magnitude more closely approximates the original signal by varying an amplification ratio depending on the magnitude of an input analog audio signal so that the input analog audio signal can be amplified to maximum possible amplitude corresponding to the number of bits that can be stored when converting the analog audio signal into digital data. The amplitude of an amplified analog audio signal also can be reconstructed if necessary, thereby providing better sound quality with the same level of sound.
