Histogram equalization (HEQ) belongs to such a category of algorithms and has proved to be effective on purpose and therefore taken here as reference. \itemrv{~} \itemcc{} \itemut{multi-channel audio processing; feature statistics normalization; histogram equalization; speech recognition; speaker recognition} \itemli{doi:10.1016/j.neucom.2011.05.035} \end
