ReZound is a digital audio editor, primarily for, but not limited to the Linux operating system. Licensed under the GNU GPL, ReZound is free software. Presently, ReZound's focus is on editing audio files for permanent change as opposed to arranging and/or filtering existing audio files to produce a composite work. It can optionally load a variety of audio file formats being dependent upon several audio file libraries.
ReZound implements a standard set of editing tools and digital filters (some these tools with useful twists on the usual theme). Additionally, it supports loading LADSPA plugins.
