Frequency, developed for PowerPC based Macintosh computers by Jonas Åström, is a basic audio spectral editor.  Frequency includes an editing brush of selectable size which can increase or decrease the audio level within selected regions.  The program was available free of charge but is no longer supported and will not run on newer Macintoshes that do not include Rosetta.
