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 13):
An apparatus according to  claim 12 ,\n wherein the input head-related transfer function is represented in a spectral domain, wherein the selected filter curve is represented in the spectral domain, or the modified filter curve is represented in the spectral domain, and\n wherein the filter information determiner is configured to determine the modified head-related transfer function by adding spectral values of the selected filter curve or of the modified filter curve to spectral values of the input head-related transfer function, or \n the filter information determiner is configured to determine the modified head-related transfer function by multiplying spectral values of the selected filter curve or of the modified filter curve and spectral values of the input head-related transfer function, or \n the filter information determiner is configured to determine the modified head-related transfer function by subtracting spectral values of the selected filter curve or of the modified filter curve from spectral values of the input head-related transfer function, or by subtracting spectral values of the input head-related transfer function from spectral values of the selected filter curve or of the modified filter curve, or \n the filter information determiner is configured to determine the modified head-related transfer function by dividing spectral values of the input head-related transfer function by spectral values of the selected filter curve or of the modified filter curve, or by dividing spectral values of the selected filter curve or of the modified filter curve by spectral values of the input head-related transfer function.
