APPARATUS AND METHOD FOR GENERATING A PLURALITY OF PARAMETRIC AUDIO STREAMS AND APPARATUS AND METHOD FOR GENERATING A PLURALITY OF LOUDSPEAKER SIGNALS.

摘要

An apparatus (100) for generating a plurality of parametric audio streams ( 125) (θi, Ψi, Wi) from an input spatial audio signal (105) obtained from a recording in a recording space comprises a segmentor (110) and a generator (120). The segmentor (110) is configured for providing at least two input segmental audio signals (115) (Wi, Xi, Yi, Zi) from the input spatial audio signal (105), wherein the at least two input segmental audio signals (1 15) (Wi, Xi, Yi, Zi) are associated with corresponding segments (Segi) of the recording space. The generator (120) is configured for generating a parametric audio stream for each of the at least two input segmental audio signals (115) (Wi, Xi, Yi, Zi) to obtain the plurality of parametric audio streams (125) (θi, Ψi, Wi).
