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 12):
The method in accordance with  claim 1 , wherein:\n i. a test signal is reproduced by loudspeakers through a first sub-band, a. the testsignal is reproduced by headphones through the first sub-band, b. evaluating the sound attributes like sound level of the test signal reproduced by the headphones through the first sub-band with the test signal reproduced by the loudspeakers through the first sub band and setting and storing the sound attributes like sound level of the headphones to be essentially the same as in the loudspeakers at the sub-band, and c. repeating the above procedure with the test signal through several sub-bands.
