Abstract
The present invention relates to a device, such as an audio communication device, for combining a plurality of microphone signals x(k) into a single output signal y(k). The device comprises processing means configured to calculate control signals f(k), and control means configured to select which microphone signal x(k) or which combination of microphone signals x(k) to use as output signal y(k) based on said control signals f(k). To improve the selection, the device comprises linear prediction filters for calculating linear prediction residual signals e(k) from the plurality of microphone signals x(k), and the processing means is configured to calculate the control signals f(k) based on said linear prediction residual signals e(k).
