Abstract
The present technology relates to a signal processing device, method, and program that can improve encoding efficiency. A signal processing device includes: an acquisition unit that acquires reverb information including at least one of space reverb information specific to a space around an audio object or object reverb information specific to the audio object and an audio object signal of the audio object; and a reverb processing unit that generates a signal of a reverb component of the audio object on the basis of the reverb information and the audio object signal. The present technology can be applied to a signal processing device.
Claims7
A signal processing device comprising:
- an acquisition unit that acquires reverb information including at least one of space reverb information specific to a space around an audio object or object reverb information specific to the audio object and an audio object signal of the audio object;
- and
- a reverb processing unit that generates a signal of a reverb component of the audio object on a basis of the reverb information and the audio object signal, wherein in a case where identification information indicating past reverb information is acquired by the acquisition unit, the reverb processing unit generates a signal of the reverb component on a basis of the reverb information indicated by the identification information and the audio object signal.
A signal processing method comprising:
- acquiring, by a signal processing device, reverb information including at least one of space reverb information specific to a space around an audio object or object reverb information specific to the audio object and an audio object signal of the audio object;
- and
- generating, by the signal processing device, a signal of a reverb component of the audio object on a basis of the reverb information and the audio object signal, wherein in a case where identification information indicating past reverb information is acquired, a signal of the reverb component is generated on a basis of the reverb information indicated by the identification information and the audio object signal.
A non-transitory computer readable medium containing instructions that, when executed by a processing device, perform a signal processing method comprising:
- acquiring reverb information including at least one of space reverb information specific to a space around an audio object or object reverb information specific to the audio object and an audio object signal of the audio object;
- and
- generating a signal of a reverb component of the audio object on a basis of the reverb information and the audio object signal, wherein in a case where identification information indicating past reverb information is acquired, a signal of the reverb component is generated on a basis of the reverb information indicated by the identification information and the audio object signal.
