摘要

An encoding apparatus, an encoding method, a decoding apparatus, a decoding method, a reproducing apparatus and a reproducing method, are present with which sound effects for a highly efficiently encoded digital signal can be performed easily without a deterioration of the signal quality. Normalization information of the digital signal is changed (119..122) corresponding to a user's operation on the time base so as to perform a sound effect process.
