Claim Text:
1. A computer implemented method for maintaining spatial stability of a sound field comprising: calculating one or more balance gains for two or more microphone signals, where each of the two or more microphone signals is from a corresponding one of two or more microphones, the one or more balance gains represent a detected balance of a spatial image of the sound field received by the microphones; calculating one or more signal values for each of the two or more microphone signals; limiting differences between corresponding one or more signal values for each of the two or more microphone signals; and maintaining the detected balance of the sound field in two or more output signals generated by gain adjusting the two or more microphone signals taking into account the one or more balance gains and the limited one or more signal values for each of the two or more microphone signals.
