In a method and a media system of/for generation of at least one output signal (HPL,HPR) from at least one input signal belonging to a second set of sound signals (M) having a related second set of Head Related Transfer Functions, in which the media system can be a TV, a CD player, a DVD player, a Radio, a display, an amplifier, a headphone or a VCR, the method includes the steps of determining, for each signal in the second set of sound signals, a weighted relation (14) including at least one signal belonging to a third set of intermediate sound signals (CHI1, CHI2) and at least one weight value (Weights); determining a first set of Head Related Transfer Functions (HRTFs) based on the second set of sound signals, the second set of Head Related Transfer Functions and the weighted relation; and transferring at least one signal belonging to the third set of intermediate sound signals by means of at least one HRTF belonging to said first set of Head Related Transfer Functions in order to generate at least one output signal belonging to said first set of sound signals. Hereby, in the end, fewer HRTFs are determined for a subsequent transfer of input signal(s) to output signal(s). Accordingly, few convolutions are required.
A method of generating, in a media system, at least one output signal belonging to a first set of sound signals from at least one input signal belonging to a second set of sound signals having a related second set of Head Related Transfer Functions, said method comprising the steps of determining, for each signal in the second set of sound signals, a weighted relation comprising at least one signal belonging to a third set of intermediate sound signals and at least one weight value;
A media system for generating at least one output signal belonging to a first set of sound signals from at least one input signal belonging to a second set of sound signals having a related second set of Head Related Transfer Functions, said media system comprising:
A method of generating, in a media system, at least one output signal belonging to a first set of sound signals from at least one input signal belonging to a second set of sound signals having a related second set of Head Related Transfer Functions, said method comprising the steps of
