VoosteQ is a Japan-based audio software developer specializing in analog-modeling plugins for music production and mixing. The company also licenses its core DSP technology to third-party audio companies, and describes its team as a group of sound producers, engineers, programmers, and musicians.

The brand's flagship product is Material Comp, a compressor plugin built around VoosteQ's proprietary DFP (Division of Force Processing) circuit-modeling engine. It bundles multiple compressor models, analog preamp saturation options, circuit simulations captured from hardware units, and mix-glue processors in a single interface. Their second major release, Model N Channel, is a channel strip that models a classic British preamp, compressor, equalizer, and transformer chain.

VoosteQ plugins are available in VST, VST3, Audio Units, and AAX formats for macOS and Windows, and have gained attention in communities like KVR Audio and Gearspace for their CPU efficiency and saturation character.

VoosteQ has 1 product cataloged on Equipboard, including Channel Strip Plugins.
