SIGNAL PROCESSING DEVICE AND METHOD, AND PROGRAM

Abstract:

The present technology relates to a signal processing device, a signal processing method, and a program that enable more efficient sound reproduction. A signal processing device includes an order determination unit that determines an order for limiting an operation amount of an operation related to a rotation matrix corresponding to head rotation of a listener, a rotation operation unit that rotates a head-related transfer function of a spherical harmonic domain by the operation in which the rotation matrix is limited by the order, and a synthesis unit that generates a headphone drive signal by synthesizing the head-related transfer function after rotation obtained by the operation with a sound signal in the spherical harmonic domain. The present technology can be applied to an audio processing device.
