The present invention provides a method and system for processing an input seismic record to suppress noise energy, for example multiple energy, and to enhance signal. A primary signal component is determined from an input seismic record. A residual record is obtained from the input seismic record and the determined primary component record, for example, by determining a difference of the two records. A next primary signal component record is then obtained from the residual record. The primary component record and the next primary component record are combined to form a reconstructed record. A subsequent residual record may then be obtained and further primary signal components extracted.
