Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. This configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent. The object position metadata contains the appropriate allocentric frame of reference information required to play the sound correctly using the available speaker positions in a room that is set up to play the adaptive audio content.

The present technology relates to a signal processing device, signal processing method, and program capable of providing a higher realistic feeling.

A signal processing device includes: an acquisition unit that acquires audio data of an audio object and metadata including position information indicating a position of the audio object and direction information indicating a direction of the audio object; and a signal generation unit that generates a reproduction signal for reproducing a sound of the audio object at a listening position on the basis of listening position information indicating the listening position, listener direction information indicating a direction of a listener at the listening position, the position information, the direction information, and the audio data. The present technology is applicable to a transmission reproduction system.

[object] To provide a headphone device in which the influence of individual differences in virtual sound field reproduction is less likely to occur and which may listen external sounds naturally, [solution] A left-side headphone body and a right-side headphone body include speaker arrays which are formed of a plurality of speaker units which are arranged to surround auricles, respectively. The speaker array of the headphone body reproduces a sound field inside a closed curved surface in the vicinity of the auricle using wave field synthesis, and since reverberation or a diffraction effect occurs in the ear of each individual, the influence caused by individual differences is less likely to occur. In addition, the speaker array has the plurality of the speaker units arranged to surround the auricle and is not of a shape that blocks the ear of the listener, and then the external sound can be heard naturally.
