1. A method for sound field reproduction into a listening area of spatially encoded first audio input signals according to sound field description data using an ensemble of physical loudspeakers, comprising the steps of: computing reproduction subspace description data from loudspeaker positioning data describing the subspace in which virtual sources can be reproduced with the physically available setup; extracting second audio input signals and third audio input signals with associated sound field description data, wherein second audio input signals comprise spatial components of the first audio input signals located within the reproducible subspace and third audio input signals comprise spatial components of the first audio input signals located outside of the reproducible subspace; performing a spatial analysis on second audio input signals for extracting fourth audio input signals corresponding to localizable sources within the reproducible subspace with associated source positioning data; merging remaining components of second audio input signals after spatial analysis and third audio input signals into fifth audio input signals with associated sound field description data for reproduction within the reproducible subspace; and, computing loudspeaker alimentation signals from fourth audio input signals and fifth audio input signals according to loudspeaker positioning data, localizable sources positioning data and sound field description data.
