    • 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.
    • 在用于从属于具有相关的第二组头相关传递函数的第二组声音信号(M)的至少一个输入信号生成至少一个输出信号(HPL,HPR)的方法和媒体系统中, 其中媒体系统可以是电视,CD播放器,DVD播放器,收音机,显示器,放大器,耳机或VCR,该方法包括以下步骤:针对第二组声音中的每个信号 信号,包括属于第三组中间声音信号(CHI1,CHI2)和至少一个重量值(重量)的至少一个信号的加权关系(14); 基于第二组声音信号确定第一组头相关传送函数(HRTF),第二组头相关传递函数和加权关系; 以及通过属于所述第一组头相关传递函数的至少一个HRTF传送属于第三组中间声音信号的至少一个信号,以便产生属于所述第一组声音信号的至少一个输出信号。 因此,最终确定用于随后将输入信号传送到输出信号的HRTF较少。 因此,需要很少的卷积。
