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 26):
A non-transitory digital storage medium having a computer program stored thereon to perform the method for providing direction modification information, said method comprising:\n for each loudspeaker of a plurality of loudspeakers, replaying a replayed audio signal by said loudspeaker and recording sound waves emitted from said loudspeaker when replaying said replayed audio signal by two microphones to acquire a recorded audio signal for each of the two microphones, wherein a first one of the plurality of loudspeakers is located at a first position at a first height, and wherein second one of the of the plurality of loudspeakers is located at a second position being different from the first position, at a second height, being different from the first height, determining a plurality of binaural room impulse responses by determining a binaural room impulse response for each loudspeaker of the plurality of loudspeakers depending on the replayed audio signal being replayed by said loudspeaker and depending on each of the recorded audio signals being recorded by each of the two microphones when said replayed audio signal is replayed by said loudspeaker, and generating at least one filter curve depending on two of the plurality of binaural room impulse responses, wherein the direction modification information depends on the at least one filter curve; when said computer program is run by a computer.
