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 3):
The method in accordance with  claim 1  for calibrating a stereo headphone, the method further comprising steps for calibrating each driver or ear cup of the headphone against a set reference ear cup or driver and storing the calibration settings in a memory of an amplifier, wherein the amplifier has signal processing properties.
