Abstract:
1. A device for processing audio data comprising: a summation unit configured to receive a number of audio input signals for generating a summation signal; a filter unit configured to filter said summation signal dependent on filter coefficients resulting in at least two audio output signals, and a parameter conversion unit configured to receive position information, which is representative of spatial positions of sound sources of said audio input signals, and spectral power information which is representative of a spectral power of said audio input signals, wherein the parameter conversion unit is configured to generate said filter coefficients on the basis of the position information and the spectral power information; and a scaling unit configured to scale the audio input signals based on gain factors generated by the parameter conversion unit; wherein the parameter conversion unit is further configured to receive transfer function parameters and generate said filter coefficients in dependence on said transfer function parameters; and the device being characterized by the parameter conversion unit being arranged to generate the filter coefficients in response to an averaged set of spatial parameters determined by a weighting of spatial parameters of each sound source depending on an energy of each sound source in a frequency band.
