Abstract
A bandwidth extension parameter generation device includes: a derivation unit which derives a high-band signal representing a high-band portion of an input sound signal; and a calculation unit which calculates a tone parameter and a floor parameter, the tone parameter indicating a magnitude of energy of a tone component of the high-band signal, the floor parameter indicating a magnitude of energy of a floor component obtained by subtracting the tone component from the high-band signal.
