摘要： An audio signal processor for providing ambient signal channels on the basis of an input audio signal, is configured to extract an ambient signal on the basis of the input audio signal. The signal processor is configured to distribute the ambient signal to a plurality of ambient signal channels in dependence on positions or directions of sound sources within the input audio signal, wherein a number of ambient signal channels is larger than a number of channels of the input audio signal.
