Abstract
There are disclosed an apparatus for generating an encoded audio scene, and an apparatus for decoding and/or processing an encoded audio scene; as well as related methods and non-transitory storage units storing instructions which, when executed by a processor, cause the processor to perform a related method. An apparatus for processing an encoded audio scene may include, in a first frame, a first soundfield parameter representation and an encoded audio signal, wherein a second frame is an inactive frame, the apparatus including: an activity detector for detecting that the second frame is the inactive frame; a synthetic signal synthesizer for synthesizing a synthetic audio signal for the second frame using the parametric description for the second frame; an audio decoder for decoding the encoded audio signal for the first frame; and a spatial renderer for spatially rendering the audio signal for the first frame using the first soundfield parameter representation and using the synthetic audio signal for the second frame, or a transcoder for generating a meta data assisted output format including the audio signal for the first frame, the first soundfield parameter representation for the first frame, the synthetic audio signal for the second frame, and a second soundfield parameter representation for the second frame.
