<p>If a mode calculating section (52) judges that an inputted modulated signal is nearly in a no-sound state, the interpolation width determined by an interpolation width calculating section (53) is increased, whereas if the mode calculating section (52) judges that the inputted modulated signal contains a lot of high-frequency components, the interpolation width determined by the interpolation width calculating section (53) is decreased.</p> |
