Abstract:
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.
