The present technology pertains to an audio processing device with which 7.1-channel audio data can be downmixed to 2-channel audio data. A coefficient for downmixing 7.1-channel audio data to 2-channel audio data is set from a coefficient for downmixing from 7.1-channel audio data to 5.1-channel audio data as defined by the MPEG4 (Moving Picture Experts Group 4) audio standard, and a coefficient for downmixing from 5.1-channel audio data to 2-channel audio data as defined by the standard, and then is stored in a 2-channel downmixing coefficient unit (22). A 2-channel downmixing unit (21) uses the coefficient stored in the 2-channel downmixing coefficient unit (22) to downmix 7.1-channel audio data to 2-channel audio data. The present technology can be applied to audio processing device. |
