Abstract: An input unit receives input of an assumed listening position of sound of an object, which is a sound source, and outputs assumed listening position information indicating the assumed listening position. A position information correction unit corrects position information of each object on the basis of the assumed listening position information to obtain corrected position information. A gain/frequency characteristic correction unit performs gain correction and frequency characteristic correction on a waveform signal of an object on the basis of the position information and the corrected position information. A spatial acoustic characteristic addition unit further adds a spatial acoustic characteristic to the waveform signal resulting from the gain correction and the frequency characteristic correction on the basis of the position information of the object and the assumed listening position information. The present technology is applicable to an audio processing device.
