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 5):
The method of  claim 3 , wherein the approximation of aspects of at least one head related transfer function of at least one human or dummy head or numerical head model comprises at least one of:\n a difference between at least one of the direct and indirect head related transfer function, the amplitude response of the direct and indirect head related transfer function, and the phase response of the direct and indirect head related transfer function; a difference between the amplitude transfer function of the indirect and direct head related transfer function respectively for the frontal direction (\u03c6, \u03bd=0\u00b0), and the corresponding amplitude transfer function of the direct and indirect head related transfer function for a second direction; a sum of at least one of, the direct and indirect head related transfer function, and the amplitude transfer function of the direct and indirect head related transfer function; an average of at least one of the respective direct and indirect head related transfer function, the respective amplitude response of the direct and indirect head related transfer function, and the respective phase response of the direct and indirect head related transfer function from multiple human individuals for a similar or identical relative source position; approximating an amplitude transfer function using minimum phase filters, approximating an excess delay using analog or digital signal delay; approximating an amplitude transfer function using finite impulse response filters; approximating an amplitude transfer function by using sparse finite impulse response filters; and\n a compensation transfer function for amplitude response alterations caused by the application of filters that approximate aspects of head related transfer functions.
