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 13):
The method of  claim 11 , wherein distributing at least one audio input signal over the multitude of virtual sound sources comprises at least one of:\n distributing the audio input signal over two virtual sound sources using amplitude panning; distributing the audio input signal over three virtual sound sources using vector based amplitude panning; distributing the audio input signal over four virtual sound sources using bilinear interpolation of representations of the respective virtual sound source directions in a two-dimensional Cartesian coordinate system; distributing the audio input signal over a multitude of virtual sound sources using stepwise linear interpolation of two-dimensional Cartesian coordinates representing the respective virtual sound source directions; encoding the at least one audio input signal in an ambisonics format, decoding the ambisonics signal using multiplication with an inverse or pseudoinverse decoding matrix derived from the geometrical layout of the virtual source directions and applying the resulting signals to the respective virtual sound sources; encoding the at least one audio input signal in an ambisonics format, manipulating the sound field represented by the ambisonics format, and decoding the manipulated ambisonics signal using multiplication with an inverse or pseudoinverse decoding matrix derived from the geometrical layout of the virtual source directions and applying the resulting signals to the respective virtual sound sources.
