Abstract:
The present technology relates to an audio processing device and method and a program, in which sound can be more efficiently reproduced. An audio processing device includes: a matrix generation unit which generates a vector for each time-frequency with a head-related transfer function obtained by spherical harmonic transform by spherical harmonics as an element by using only the element corresponding to a degree of the spherical harmonics determined for the time-frequency or on the basis of the element common to all users and the element dependent on an individual user; and a head-related transfer function synthesis unit which generates a headphone drive signal of a time-frequency domain by synthesizing an input signal of a spherical harmonic domain and the generated vector. The present technology can be applied to an audio processing device.

Claim (Index 2):
The audio processing device according to  claim 1 , wherein the matrix generation unit generates the vector on the basis of the element common to all the users and the element dependent on the individual user, which are determined for each time-frequency.
