Abstract:
An audio sound signal encoding device includes: a converter that adds up all multiple channel signals included in multichannel voice sound input signals to generate an addition signal and generates a difference signal between channels of the multiple channel signals; a first encoder that encodes the addition signal in a coding mode in accordance with a characteristic of the addition signal to generate first encoded data; a second encoder that encodes the difference signal in the coding mode that was used for encoding the addition signal, to generate second encoded data; and a multiplexer that multiplexes the first encoded data and the second encoded data to generate multichannel encoded data.

Claim (Index 7):
An audio sound signal decoding device comprising:\n an inverse multiplexer that separates multichannel encoded data outputted from an audio sound signal encoding device into first encoded data and second encoded data,\n the first encoded data being generated in the audio sound signal encoding device by encoding an addition signal in a coding mode in accordance with a characteristic of the addition signal, the addition signal being generated by adding up all multiple channel signals included in multichannel voice sound input signals, \n the second encoded data being generated in the audio sound signal encoding device by encoding a difference signal in the coding mode that was used for encoding the addition signal, the difference signal being difference between channels of the multiple channel signals; \n a first decoder that decodes the first encoded data in the coding mode that was used for encoding the addition signal, to obtain a decoded addition signal; a second decoder that decodes the second encoded data in the coding mode that was used for encoding the addition signal, to obtain a decoded difference signal; and an inverse converter that performs weighted addition on the decoded addition signal and the decoded difference signal to generate decoded audio sound signals.
