reFuse Software is an independent audio plugin developer founded by Leigh Marble in 2002 in Portland, Oregon. The company's earliest release was a standalone application called reFuse, which provided a bridge between Pro Tools and Propellerhead Reason before ReWire integration became available. Since then, the company has focused on producing niche processing tools and utilities for music production, post-production, and sound design.

The catalog spans creative effects and workflow utilities. Lowender is a subharmonic generator used to reinforce sub-bass content in mixing and post-production. Bucketverb models a vintage Panasonic bucket-brigade (BBD) delay chip to produce lo-fi, dark ambient reverb textures. Mulligan is a standalone companion application for Pro Tools that lets engineers control plugin parameters with any MIDI controller. The company also maintains a set of freeware tools, including Flipper, Cheap RTA, and Simple Meter.

Plugins are offered in AAX, VST3, and Audio Unit formats for macOS and Windows, with native Apple Silicon support, and licenses are sold as perpetual with free lifetime updates.

reFuse Software has 1 product cataloged on Equipboard, including Enhancer Plugins.
