Abstract:
An apparatus for generating a filtered audio signal from an audio input signal includes a filter information determiner being configured to determine filter information depending on input height information wherein the input height information depends on a height of a virtual sound source. Moreover, the apparatus includes a filter unit being configured to filter the audio input signal to obtain the filtered audio signal depending on the filter information. The filter information determiner is configured to determine the filter information using selecting, depending on the input height information, a selected filter curve from a plurality of filter curves, or the filter information determiner is configured to determine the filter information using determining a modified filter curve by modifying a reference filter curve depending on the elevation information.
