Infrasonic Audio is a small Colorado-based builder of Eurorack modules and digital music hardware, founded in 2022 as a one-person operation. The company focuses on uniquely digital timbres and unconventional signal processing within the modular synthesizer format.

Its catalog centers on three modules: the Warp Core, a complex stereo phase-distortion oscillator that uses eight continuously variable algorithms across two series-routed slots to shape harmonics from a sine lookup table; the WC:EX, a 4HP expander adding envelope generator and VCA functionality to the Warp Core; and the Disentangler, a 4HP stereo width and mid-side processor. A collaboration with WMD called Cosmic Debris was announced as a delay and reverb engine aimed at modular users.

Infrasonic Audio also maintains an open-source VCV Rack port of its hardware, allowing the Warp Core and related modules to be used inside the virtual modular environment. The brand has built a niche reputation among Eurorack users for compact, sonically distinctive digital modules with a focus on phase distortion synthesis and stereo processing.

Infrasonic has 3 products cataloged on Equipboard, including Audio Interfaces and MIDI Keyboard Controllers. Their gear is featured by 2 artists, with the strongest followings in Electronic. Notable users include Exaya Music and Sebastien Benett.
