Original Abstract Submitted

a method for generating a parametric spatial audio stream, the method including: obtaining at least one mono-channel audio signal from at least one close microphone; obtaining at least one of: at least one reverberation parameter; at least one control parameter configured to control spatial features of the parametric spatial audio stream; generating, based on the at least one reverberation parameter, at least one reverberated audio signal from a respective at least one mono-channel audio signal; generating at least one spatial metadata parameter based on at least one of: the at least one mono-channel audio signal; the at least one reverberated audio signal; the at least one control parameter; and the at least one reverberation parameter; and encoding the at least one reverberated audio signal and the at least one spatial metadata parameter to generate the spatial audio stream.
