ReZound is a digital audio editor, primarily for, but not limited to the Linux operating system. Licensed under the GNU GPL,[1] 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.
