AUDIO OBJECT RENDERER, METHODS FOR DETERMINING LOUDSPEAKER GAINS AND COMPUTER PROGRAM USING PANNED OBJECT LOUDSPEAKER GAINS AND SPREAD OBJECT LOUDSPEAKER GAINS

摘要

An audio object renderer (200; 1200) for determining loudspeaker gains (214,1214,1214a-c) describing gains for an inclusion of one or more audio object signals (1260) into a plurality of loudspeaker signals (1262a-1262c) on the basis of an object position information (210,1210, azi, ele) and an object feature information or a spread information (1212) is configured to obtain panned object loudspeaker gains (202a, 1232, g) using a point source panning (202,1230) of the audio object. The audio object renderer is configured to obtain spread object loudspeaker gains (206a, 1242, gOS) considering the object position information (210,1210, azi, ele) and the object feature information or spread information (1212). The audio object renderer is configured to combine the panned object loudspeaker gains (202a, 1232, g) and the spread object loudspeaker gains (206a, 1242, gOS) in such a manner, that there is always a contribution of the panned object loudspeaker gains, in order to obtain combined loudspeaker gains (214, 1214, 1214a-c). Methods and computer programs are also described.
