摘要：An encoding apparatus for highly efficiently encoding an input digital signal

includes a band dividing means, an encoding means, a normalization processing means fornormalizing a signal component of each block encoded by the encoding means andgenerating a normalization signal, a quantization coefficient calculating means, a bitallocating means for deciding the number of allocated bits for each block correspondingto the quantization coefficients calculated by the quantization coefficient calculatingmeans, a normalization information changing means for gradually changing thenormalization information generated by the normalization processing meanscorresponding to a user's operation on a time base, and an encoded data generatingmeans.
