Abstract
Binaurally reproduced audio signals are often perceived as unnatural. For example, speech intelligibility may be reduced. For improving the spatial reproduction of audio signals, the invention enables binaurally virtualizing a single-channel audio signal only partially by filtering. A degree of binaural virtualization for the audio signal based on one or more processing parameters (P, P, P) may be freely chosen. A control allows a smooth transition between a completely binaural virtualization based on HRTF and a non-binaural virtualization corresponding to panning. A first range (B) starts with a completely binaural virtualization and the HRTFs that are commonly used for this. 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. In a subsequent second range (B) that leads to a completely panning-like virtualization, the resulting phase is reduced, or adjusted to the panning phase of 0°. By selecting one or more processing parameters, different audio signals may be binaurally virtualized to different degrees before being superposed to each other.
