Abstract
The present technology relates to an audio processing apparatus capable of downmixing 7.1-ch audio data to 2-ch audio data. A coefficient for downmixing 7.1-ch audio data to 2-ch audio data is set from a coefficient for downmixing 7.1-ch audio data to 5.1-ch audio data specified by a Moving Picture Experts Group 4 (MPEG4) audio standard and a coefficient for downmixing 5.1-ch audio data to 2-ch audio data specified by the standard, and stored in a 2-ch downmixing coefficient unit. A 2-ch downmixing unitdownmixes 7.1-ch audio data to 2-ch audio data using a coefficient stored in the 2-ch downmixing coefficient unit. The present technology can be applied to an audio processing apparatus.
