Abstract:
A method for operating a microphone system, comprising the steps of:(a) detecting a sound at a plurality of spatially distributed locations; (b) simultaneously evaluating at least one variable of the sound detected by each of the microphones; (c) weighting the locations of the microphones and combining audio signals from the microphones based on the evaluating step (b); (d) tracking a changed location in 3-dimensional space of a source of the sound based on a directivity of the microphone system by shifting at least one of the variables of the microphone signals; (e) optimizing in 3-dimensional space a virtual microphone location in relation to the position in 3-dimensional space of a movable sound source; (f) feeding the signals from the microphones to a transmission device after the evaluating step (b).
