Abstract:
The present technology relates to a signal processing device, a signal processing method, and a program which are capable of improving encoding efficiency.
The signal processing device includes a correction unit configured to correct an audio signal of an audio object based on a gain value included in metadata of the audio object, and a quantization unit configured to calculate auditory psychological parameters based on a signal obtained by the correction and to quantize the audio signal. The present technology can be applied to an encoding device.
