Abstract
The present invention is based on the finding that a sound-reproduction system, which can generate a spatial sound impression in a reproduction environment, can be efficiently and intuitively controlled by means of a graphic user interface when an impulse response associated with a spatial direction with respect to the reproduction environment is graphically represented, and when the possibility is created for a user to change the impulse response graphically so that, based on the user input of a change, the changed impulse response can be graphically represented and the changed graphical representation can be detected, in order to control the sound-reproduction system. Since it is system-theoretically possible to describe all known linear signal processing operations by impulse responses, it is possible, with the inventive graphic user interface, to provide a sound mixer, through a graphical representation, with an intuitive access to sound effects depending on the direction.
