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 HSI−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 HRI−1(ω) H*(ω) a response α(ω) is headphone reproduction bandwidth, σ(ω) an estimation of the regularization needed inside that bandwidth.
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, wherein the method comprises using a sigma inversion equation for the equalization:
An active stereo/binaural headphone system including headphones with at least one driver for each ear cup and an amplifier connected to the headphones by a cable, the system comprising:
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:
