Abstract:
1. An apparatus for generating a low-frequency channel for a low-frequency loudspeaker, comprising: a first provider for providing a plurality of audio objects, the plurality of audio objects comprising at least a first audio object and a second audio object, each audio object having an object signal and an object description associated with the object signal; a calculator for calculating an audio object scaling value for each audio object in dependence on the object description associated with the object signal so that at least a first audio object scaling value for the first audio object and a second audio object scaling value for the second audio object is obtained; a scaler for scaling each object signal with an associated audio object scaling value so as to obtain at least a first scaled object signal for the first audio object and a second scaled object signal for the second audio object; a summer for summing at least the first scaled object signal and the second scaled object signal so as to obtain a composite signal; and a second provider for providing the low-frequency channel for the low-frequency loudspeaker on the basis of the composite signal.
