EFFICIENT PERSONALIZATION OF HEAD-RELATED TRANSFER FUNCTIONS FOR IMPROVED VIRTUAL SPATIAL AUDIO |
| 摘要 |
A method generating a virtual audio signal for a listener. The method includes estimating spherical harmonic coefficients based on an individual character of the listener. The estimated spherical harmonic coefficients are compared to a distribution of known spherical harmonic coefficients. The estimated spherical harmonic coefficients are iteratively updated and compared to the distribution of known spherical harmonic coefficients until convergence. The individual character and the converged spherical harmonic coefficients are then applied to a mono-channel sound. |

1. A method generating a virtual audio signal for a listener, the method comprising:
estimating spherical harmonic coefficients based on an individual character of the listener; comparing the estimated spherical harmonic coefficients to a distribution of known spherical harmonic coefficients; iteratively updating the estimated spherical harmonic coefficients and comparing the updated and estimated spherical harmonic coefficients to the distribution of known spherical harmonic coefficients until convergence; and applying the individual character and the converged spherical harmonic coefficients to a mono-channel sound. |
