A signal processing device includes a rotation operation unit that rotates a head-related transfer function in a spherical harmonic domain by an operation on the basis of a rotation matrix corresponding to rotation of a head of a listener, the operation in which an order of the rotation matrix is limited, and a synthesis unit that synthesizes the head-related transfer function after rotation obtained by the operation and a sound signal of the spherical harmonic domain to generate a headphone drive signal.
