Claim:
1. A method for outputting a modified audio signal, the method comprising: receiving from a user an input indicating an angle using a graphical user interface; determining a parameter for a head-related transfer function based on the received input indicating the angle; modifying an audio signal in accordance with the head-related transfer function based on the determined parameter; and outputting the modified audio signal; wherein the input indicating the angle is a graphical input indicating the angle by adjusting a position of a calibration marker of the graphical user interface; wherein the calibration marker of the graphical user interface is associated to an immovable virtual speaker location of the graphical user interface; wherein the calibration marker of the graphical user interface and the immovable virtual speaker location of the graphical user interface lie on a geometric shape; wherein the position of the calibration marker of the graphical user interface corresponds to a perceived audio origination point; wherein the immovable virtual speaker location of the graphical user interface represents a predetermined position of a surround sound system; and receiving from the user a further input indicating a head shape of the user; wherein the parameter for the head-related transfer function is determined further based on the received further input indicating the head shape of the user.
