In this range, the HRTFs are modified by scaling and by approaching them to the gain factors of the panning while decreasing a degree of binaural virtualization. A first range (B1) starts with a completely binaural virtualization and the HRTFs that are commonly used for this. A control allows a smooth transition between a completely binaural virtualization based on HRTF and a non-binaural virtualization corresponding to panning. A degree of binaural virtualization for the audio signal based on one or more processing parameters (PC, PFC, PTC) may be freely chosen. For improving the spatial reproduction of audio signals, the invention enables binaurally virtualizing a single-channel audio signal only partially by filtering. For example, speech intelligibility may be reduced. Abstract: Binaurally reproduced audio signals are often perceived as unnatural.
