ABSTRACT:
A decoding device is a decoding device that generates frequency spectral data from an inputted encoded audio data stream, and includes: a core decoding unit for decoding the inputted encoded data stream and generating lower frequency spectral data representing an audio signal; and an extended decoding unit for generating, based on the lower frequency spectral data, extended frequency spectral data indicating a harmonic structure, which is same as an extension along the frequency axis of the harmonic structure indicated by the lower frequency spectral data, in a frequency region which is not represented by the encoded data stream.
