摘要
Stereo signal coding apparatus usable in the case of applying the intermittent transmission technology for stereo signals, without reducing the quality, to achieve a low bit rate. Stereo signal encoding apparatus for encoding a stereo signal comprising a first channel signal and second channel signal A (100), the stereo encoding unit (103), the apparatus includes an audio stereo signal of the current frame by encoding a stereo signal when it is a unit to generate a first stereo encoded data, stereo DTX encoding unit (104), encoding a stereo signal when the stereo signal of the current frame is a non-voice section and means for a monaural signal spectral parameter is a spectrum parameter of the monaural signal generated using a second channel signal and the first channel signal, a first channel signal information for the first channel signal and the second channel signal by encoding each of a second channel signal information about, and to generate a second stereo encoded data.
