A method for compensating for acoustic influence of a listening room on an acoustic output from an audio system including at least a left and a right loudspeaker (2, 3), the method comprising: determining a left frequency response LP L between a signal applied to the left speaker and a resulting power average in a listening position, determining a right frequency response LP R between a signal applied to the right speaker and a resulting power average in the listening position, designing a left compensation filter F L, designing a right compensation filter F R, during playback, applying the left compensation filter to a left input signal, and applying the right compensation filter to a right input signal, characterized by providing a simulated target function H T representing a simulated target response in the listening position, and designing the left compensation filter F L to have a left filter transfer function based on the simulated target function H T multiplied by an inverse of the left frequency response, and designing the right compensation filter F R to have a right filter transfer function based on the simulated target function H T multiplied by an inverse of the right frequency response, wherein the simulated target function is obtained by simulating the power emitted by a point source in a corner defined by three orthogonal walls into a one eights sphere limited by the three walls, and defining the simulated target function as the transfer function between the point source and the emitted power, wherein the simulated emitted power is a power average based on simulations in a plurality of points, preferably more than 12 points, distributed on the one eighth sphere. determining a left frequency response LP L between a signal applied to the left speaker and a resulting power average in a listening position, determining a right frequency response LP R between a signal applied to the right speaker and a resulting power average in the listening position, designing a left compensation filter F L, designing a right compensation filter F R, during playback, applying the left compensation filter to a left input signal, and applying the right compensation filter to a right input signal, providing a simulated target function H T representing a simulated target response in the listening position, and designing the left compensation filter F L to have a left filter transfer function based on the simulated target function H T multiplied by an inverse of the left frequency response, and designing the right compensation filter F R to have a right filter transfer function based on the simulated target function H T multiplied by an inverse of the right frequency response, wherein the simulated target function is obtained by simulating the power emitted by a point source in a corner defined by three orthogonal walls into a one eights sphere limited by the three walls, and defining the simulated target function as the transfer function between the point source and the emitted power, wherein the simulated emitted power is a power average based on simulations in a plurality of points, preferably more than 12 points, distributed on the one eighth sphere.
