The new application of non-linear approximation for spectrum processing and multiplatform software for spectrum analysis with friendly user interface is suggested. Experimental spectrum is approximated by a sum of a number of functions. Each function can be approximated on selected interval separately when other functions are subtracted from experimental spectrum. All actions can be made using graphical user interface.
