1. A method for reconstructing a time frame of an audio scene with at least a plurality of N audio signals from a bitstream, the method comprising:
receiving the bitstream comprising the N audio signals signal, wherein N>1;
decoding a downmix signal from the bitstream, the downmix signal comprising M downmix channels, wherein M>1 and each downmix channel is associated with a spatial locator of a plurality of spatial locators; and
reconstructing the N audio signals based on as an inner product of a plurality of correlation coefficients and the downmix signal, wherein the plurality of correlation coefficients correspond to one or more of the plurality of spatial locators.
