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.

A segment file acquisition unit acquires an audio stream encoded by a lossless DSD technique before a video stream corresponding to the audio stream and detects a bit rate of the audio stream. A selection unit selects the video stream to be acquired from a plurality of the video streams having different bit rates, on the basis of the bit rate detected by the segment file acquisition unit. The present disclosure can be applied to, for example, a moving image reproduction terminal or the like.
