Noise Engineering is a Southern California-based music technology company founded by Stephen and Kris McCaul. The company began making Eurorack modules and has since expanded its output to include software plugins and guitar pedals, all sharing a distinctive aesthetic that blends digital precision with experimental, often aggressive sound design.

The brand is best known for its Eurorack module families, including the Iteritas line of digital oscillators (such as the Loquelic Iteritas and Loquelic Iteritas Percido), the Versio platform of stereo DSP modules, and the compact Legio series. Their modules tend to emphasize hands-on, performance-oriented controls and are frequently associated with harsh digital timbres, percussive synthesis, and stereo effects. Alongside hardware, Noise Engineering produces plugin versions of many of its modules for use in DAWs, bringing the same sound engines to software users.

Noise Engineering has 80 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 14 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Andrew Huang, Matt Lange, and Misha Mansoor. Noise Engineering's catalog spans the full price spectrum — from entry-level options to high-end flagships.
