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 12):
The method of  claim 11 , further comprising\n tracking momentary movements, orientations or positions of the user's head using a sensing apparatus, wherein the movements, orientations or positions are tracked at least around one rotation axis (x, y, z), and at least within a certain rotation range per rotation axis, and the instantaneous virtual playback position of at least one audio input signal is kept approximately constant with respect to the user over the range of tracked head-positions, by distributing the audio input signal over a number of virtual sound sources based on at least one instantaneous rotation angle of the head.
