Abstract

The invention relates to a method for processing at least one monaural audio signal with known parameters, with the aim of generating a stereo signal allowing the perception that sound comes from any spatial position in real time by means of the use of earphones. The method is based on the division of the process into two steps, one step wherein the audio signal is prepared by being dividing into frequency sub-bands and stored in a memory, and the second step that is the spatial processing of the signal by means of the use of empirical parametric tables where the spatial localisation coordinates are inserted either by a person or by a device via an interface. Said embodiment allows this effect to be obtained in real time in devices with little computing power, without being limited thereto.
