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 10):
The audio processing device according to  claim 1 , further comprising\n a time-frequency inverse transform unit which performs time-frequency inverse transform on the headphone drive signal.
