Abstract
The present technology relates to a signal processing device and method, and a program making it possible to reduce the computational complexity of decoding at low cost. A signal processing device includes: a priority information generation unit configured to generate priority information about an audio object on the basis of a plurality of elements expressing a feature of the audio object. The present technology may be applied to an encoding device and a decoding device.
Claims17
A signal processing device comprising:
- processing circuitry configured to generate priority information about an audio object on a basis of at least one element expressing a feature of the audio object,
- wherein the element includes spread information, wherein the processing circuitry is configured to generate the priority information according to a product of a horizontal directional spread angle and a vertical directional spread angle, and wherein an audio signal of the audio object is decoded by a decoding device according to the priority information.
A signal processing method executed by processing circuitry, the method comprising:
- generating priority information about an audio object on a basis of at least one element expressing a feature of the audio object, wherein the element includes spread information, wherein the priority information is generated according to a product of a horizontal directional spread angle and a vertical directional spread angle, and wherein an audio signal of the audio object is decoded by a decoding device according to the priority information.
A non-transitory computer readable medium containing instructions that, when executed by processing circuitry, perform a process comprising:
- generating priority information about an audio object on a basis of at least one element expressing a feature of the audio object, wherein the element includes spread information, wherein the priority information is generated according to a product of a horizontal directional spread angle and a vertical directional spread angle, and wherein an audio signal of the audio object is decoded by a decoding device according to the priority information.
