PROCESS.AUDIO is an audio plugin developer and the software division of Puremix, an audio engineering education community. The company was founded by a team of music industry professionals led by producer and mixer Fab Dupont, with the stated goal of building mixing and production tools that bridge analog workflow sensibilities with modern digital technology. Its plugins are released in VST, VST3, AU, and AAX formats for macOS and Windows and use iLok for license management.

The catalog centers on mixing and creative effect tools, including Sugar (a multi-band harmonic enhancer/sweetener), Decibel (a real-time metering display), Spicerack (a saturation and distortion plugin), Ripple (a creative delay), Filter Factory (a modulated filter), and Rockruepel COMP.TWO (an emulation of the Rockruepel hardware compressor). The company also offers Protility, a free suite of utility tools aimed at track preparation and gain staging.

PROCESS.AUDIO's products are sold through the company's own store as well as third-party retailers such as Plugin Boutique and Sweetwater. The brand leans heavily on Puremix's educational footprint, pairing plugin releases with tutorials and mixing breakdowns from the engineers behind the tools.

PROCESS.AUDIO has 6 products cataloged on Equipboard, including Multi-Effect Plugins, Metering Plugins, and Saturation Plugins.
