Abstract:
According to an example aspect of the present invention, there is provided a Method for regularizing the inversion of a stereo headphone transfer function for headphone equalization, characterized by using the equation for the equalization: H S   1 - 1  ( ω ) = H *  ( ω )  H  ( ω )  2 + β ^  ( ω )  D  ( ω ) = H *  ( ω )  H  ( ω )  2 + [ α  ( ω ) + σ 2  ( ω ) ]  D  ( ω ) . in which equation H SI −1 (ω) is sigma inversion H*(ω) is complex conjugate of a response D(ω) is a delay filter introduced to produce a causal inverse H RI −1 (ω) H*(ω) a response α(ω) is headphone reproduction bandwidth, σ(ω) an estimation of the regularization needed inside that bandwidth.

Claim (Index 29):
A non-transitory computer readable medium configured to cause a method for regularizing the inversion of a stereo headphone transfer function, containing peaks and notches due to resonances and scattering produced inside the volume bound by the headphone and the listener's ear, for headphone equalization, to be performed, wherein the method comprises using a sigma inversion equation for the equalization: H S \ue89e \ue89e 1 - 1 \ue8a0 ( \u03c9 ) = H * \ue8a0 ( \u03c9 ) \uf603 H \ue8a0 ( \u03c9 ) \uf604 2 + \u03b2 ^ \ue8a0 ( \u03c9 ) \ue89e D \ue8a0 ( \u03c9 ) = H * \ue8a0 ( \u03c9 ) \uf603 H \ue8a0 ( \u03c9 ) \uf604 2 + [ \u03b1 \ue8a0 ( \u03c9 ) + \u03c3 2 \ue8a0 ( \u03c9 ) ] \ue89e D \ue8a0 ( \u03c9 ) . \u2003 in which equation\n H SI \u22121 (\u03c9) is sigma inversion \n H*(\u03c9) is complex conjugate of a response \n D(\u03c9) is a delay filter introduced to produce a causal inverse H RI \u22121 (\u03c9) \n H*(\u03c9) a response \n \u03b1(\u03c9) is headphone reproduction bandwidth, \n \u03c3(\u03c9) an estimation of the regularization needed inside that bandwidth.
