Abstract
An audio processing arrangement () comprises a plurality of audio sources () generating input audio signals, a processing circuit () for deriving processed audio signals from the input audio signals, a combining circuit () for deriving a combined audio signal from the processed audio signals, and a control circuit () for controlling the processing circuit in order to maximize a power measure of the combined audio signal and for limiting a function of gains of the processed audio signals to a predetermined value. In accordance with the present invention, the audio processing arrangement () comprises a pre-processing circuit () for deriving pre-processed audio signals from the input audio signals to minimize a cross-correlation of interferences comprised in the input audio signals. The pre-processed signals are provided to the processing circuit () instead of the input audio signals.
