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.

Claim (Index 21):
An apparatus according to  claim 19 ,\n wherein the filter curve generator is configured to determine a plurality of head-related transfer functions from the plurality of binaural room impulse responses by extracting a head-related transfer function from each of the binaural room impulse responses, wherein the plurality of head-related transfer functions are represented in a spectral domain, wherein a height value is assigned to each of the plurality of head-related transfer functions, wherein the filter curve generator is configured to generate two or more filter curves, wherein the filter curve generator is configured to generate each of the two or more filter curves by subtracting spectral values of a second one of the plurality of head-related transfer functions from spectral values of a first one of the plurality of head-related transfer functions, or by dividing the spectral values of the first one of the plurality of head-related transfer functions by the spectral values of the second one of the plurality of head-related transfer functions, wherein the filter curve generator is configured to assign a height value to each of the two or more filter curves by subtracting the height value being assigned to the first one of the plurality of head-related transfer functions from the height value being assigned to the second one of the plurality of head-related transfer functions, and wherein the direction modification information comprises each of the two or more filter curves and the height value being assigned to said filter curve.
