Abstract.   Semi-automatic technique for two-channel noise suppression with asynchronous reference signal (i.e. from an external source) is presented. The technique is described in details, its efficiency is compared with the algorithms using synchronous noise recordings.
Keywords: noise suppression, acoustic noise, adaptive signal processing
