Subzix Raw

Subzix Raw is a free one-knob sub-bass enhancer for macOS. The single SUB knob tracks the pitch of your low end and adds phase-locked octave-down sub-harmonics, low-end saturation, and a touch of stereo width — turn it up and the bass gets bigger and deeper, level-matched so it just gets heavier, never louder. Works on basslines, kicks, synths, and full mixes.

One knob for bigger bass. No band-splitting or routing to set up — it tracks your pitch and adds tight, phase-locked weight underneath, for a bigger, deeper low end that stays controlled instead of turning to mud.

Formats: AU, VST3, and Standalone — Universal Binary (Apple Silicon + Intel), code-signed and notarized by Apple so it installs cleanly on macOS. Free to download.
