METHOD APPARATUS AND RECORDING MEDIUM FOR CODING OMETHOD, APPARATUS AND RECORDING MEDIUM FOR CODING OF SEPARATED TONE AND NOISE CHARACTERISTICS SPECTRF SEPARATED TONE AND NOISE CHARACTERISTIC SPECTRAL COMPONENTS OF AN ACOUSTIC SIGNAL AL COMPONENTS OF AN ACOUSTIC SIGNAL

摘要

This method comprises the steps of converting the inputted acoustic signals into the frequency component; separating the output of conversion means to the tone component and the other component (noise component); coding the tone component; coding the noise component; and generating the code string from the output of the coding step.
