Abstract
The present technology relates to a signal processing device, a method, and a program that make it possible for a user to obtain a higher realistic feeling. The signal processing device includes: an audio generation unit that generates a sound source signal according to a type of a sound source on the basis of a recorded signal obtained by sound collection by a microphone attached to a moving object; a correction information generation unit that generates position correction information indicating a distance between the microphone and the sound source; and a position information generation unit that generates sound source position information indicating a position of the sound source in a target space on the basis of microphone position information indicating a position of the microphone in the target space and the position correction information. The present technology can be applied to a recording/transmission/reproduction system.
