DECODER AND METHOD FOR A GENERALIZED SPATIAL-AUDIO-OBJECT-CODING PARAMETRIC CONCEPT FOR MULTICHANNEL DOWNMIX/UPMIX CASES

摘要

A decoder for generating an audio output signal comprising one or more audio output channels from a downmix signal comprising one or more downmix channels is provided. The downmix signal encodes one or more audio object signals. The decoder comprises a threshold determiner (110) for determining a threshold value depending on a signal energy and/or a noise energy of at least one of the of or more audio object signals and/or depending on a signal energy and/or a noise energy of at least one of the one or more downmix channels. Moreover, the decoder comprises a processing unit (120) for generating the one or more audio output channels from the one or more downmix channels depending on the threshold value.
