    摘要： A decoding device according to the present disclosure is a decoding device (100) that decodes core encoded data where a low-band spectrum of a predetermined frequency or lower has been encoded, and extended band encoded data where a high-band spectrum of a predetermined frequency or higher has been encoded based on core encoded data. The decoding device includes: an amplitude normalization unit (103) that normalizes the amplitude of the core decoded spectrum, obtained by decoding the core encoded data, by the largest value of the amplitude of the core decoded spectrum, and generates a normalized spectrum; a noise generating unit (104) that generates a noise spectrum; a first addition unit (105) that adds the noise spectrum to the normalized spectrum and generates a noise-added normalized spectrum; and an extended band decoding unit (106) that decodes the extended band encoded data using the noise-added normalized spectrum, and generates a noise-added extended band spectrum.
