Abstract:
An apparatus for generating a plurality of parametric audio streams from an input spatial audio signal obtained from a recording in a recording space has a segmentor and a generator. The segmentor is configured for providing at least two input segmental audio signals from the input spatial audio signal, wherein the at least two input segmental audio signals are associated with corresponding segments of the recording space. The generator is configured for generating a parametric audio stream for each of the at least two input segmental audio signals to obtain the plurality of parametric audio streams.
