摘要： An audio object renderer for determining loudspeaker gains describing gains for an inclusion of one or more audio object signals into a plurality of loudspeaker signals on the basis of an object position information and an object feature information or a spread information is configured to obtain panned object loudspeaker gains using a point source panning of the audio object. The audio object renderer is configured to obtain spread object loudspeaker gains considering the object position information and the object feature information or spread information. The audio object renderer is configured to combine the panned object loudspeaker gains and the spread object loudspeaker gains in such a manner, that there is a contribution of the panned object loudspeaker gains, in order to obtain combined loudspeaker gains. Methods and computer programs are also described.

摘要： 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.
