An encoding apparatus for encoding a time-series signal in a frequency domain is provided with: a spectral envelope estimating portion 2A estimating a spectral envelope, regarding absolute values of a frequency domain sample sequence corresponding to the time-series signal raised to the power of η as a power spectrum, on the assumption that η is a predetermined positive number other than 2; and an encoding portion 2B performing such encoding that changes bit allocation or that bit allocation substantially changes, for each coefficient of the frequency domain sample sequence corresponding to the time-series signal, based on the estimated spectral envelope."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoding apparatus, decoding apparatus, and method and program for the same","description":"There are provided an encoding or decoding technique capable of performing more efficient encoding or decoding than before.
