Abstract:
A method for binaural synthesis of at least one virtual sound source comprises operating a first device comprising at least four physical sound sources, wherein, when the first device is used by a user, at least two physical sound sources are positioned closer to a first ear of the user than to a second ear, and at least two physical sound sources are positioned closer to the second ear than to the first ear, and wherein, for each ear, at least two physical sound sources are configured to acoustically induce natural directional pinna cues associated with different directions of sound arrival at the ear of the user. The method further comprises receiving and processing at least one audio input signal and distributing at least one processed version of the audio input signal at least between 4 kHz and 12 kHz over at least two physical sound sources for each ear.

Claim (Index 8):
The method of  claim 6 , wherein panning factors for distribution of at least one processed audio input signal over at least two physical sound sources closer to one ear depend on the relative location of two-dimensional Cartesian coordinates representing the direction of sound arrival from at least two physical sound sources at the ear of the user and two-dimensional Cartesian coordinates representing the desired direction of sound arrival from a virtual sound source at the user or at the user's ear, and wherein the panning factors can be determined by one of:\n calculating interpolation factors by stepwise linear interpolation between the respective two-dimensional Cartesian coordinates (x, y) representing the direction of sound arrival from the at least two physical sound sources at the ear of the user at the respective two-dimensional Cartesian coordinates (x, y) representing the desired perceived direction of sound arrival from the virtual sound source at the user or at the user's ear, and combining and normalizing the interpolation factors per physical sound source; and calculating respective distance measures between the position defined by Cartesian coordinates representing the direction of the desired virtual sound source with respect to the user or the user's ear, and the positions defined by respective two-dimensional Cartesian coordinates representing the direction of sound arrival from the at least two physical sound sources at the ear of the user, and calculating distance-based panning factors.
