Abstract
The present technology relates to a signal processing device, a signal processing method, and a program, which are capable of reproducing an acoustic field more appropriately in accordance with content. A decoding unit decodes a multiplexed signal, and obtains a multichannel sound collection signal obtained by performing sound collection through a linear microphone array and spatial correction information for selecting a spatial correction scheme for correcting a spatial transfer characteristic. A spatial correction scheme selecting unit selects the spatial correction scheme on the basis of the spatial correction information, and a spatial transfer characteristic matrix generating unit outputs a spatial transfer characteristic matrix indicated by a selection result of the spatial correction scheme. A drive signal generating unit generates a speaker drive signal of a spatial frequency domain on the basis of the multichannel sound collection signal and the spatial transfer characteristic matrix. The present technology can be applied to a spatial correction controller.
