  • Publication number: 20250133366
    Abstract: Audio processor for performing audio rendering by generating rendering parameters, which determine a derivation of loudspeaker signals to be reproduced by a set of loudspeakers from an audio signal. The audio processor is configured to obtain a reverberation effect information and to perform a gain adjustment so as to determine, based on a listener position, gains for generating the loudspeaker signals for the loudspeakers from the audio signal. The audio processor is configured to use, depending on the reverberation effect information, in the gain adjustment, for at least one loudspeaker, a roll-off gain compensation function for mapping a listener-to-loudspeaker distance of the at least one loudspeaker onto a listener-to-loudspeaker-distance compensation gain for the at least one loudspeaker, for which a compensated roll-off gets monotonically shallower with increasing listener-to-loudspeaker distance.
