Abstract
There is provided such embedded encoding that the algorithmic delay of stereo coding/decoding is not larger than that of monaural coding/decoding. An encoding device () encodes a sound signal having a plurality of channels. A stereo encoding unit () obtains and outputs a stereo code representing a characteristic of difference between channels of the sound signal. A downmix unit () obtains a signal by mixing the sound signal as a downmix signal. A monaural encoding unit () encodes the downmix signal by an encoding scheme that includes processing of applying a window having overlap between frames to obtain and output a monaural code. An additional encoding unit () encodes a part of the downmix signal for a section corresponding to the overlap between a current frame and an immediately following frame to obtain and output an additional code.
