Abstract: The present technology relates to a signal processing apparatus and method, and a program that are capable of reproducing sound at an optional listening position with a high sense of reality. The signal processing apparatus includes a rendering unit that generates reproduction data of sound at an optional listening position in a target space on the basis of recording signals of microphones attached to a plurality of moving bodies in the target space. The present technology can be applied to a reproduction apparatus.
