OwItHz
Sub-oscillator harmonic synth. 12 engines targeting 0.5-500 Hz. Your subwoofer's new best friend.
What is OwItHz?
OwItHz makes frequencies you feel but can’t quite hear. A sub-oscillator harmonic synthesiser targeting 0.5-500 Hz — the range where bass meets body.
Twelve synthesis engines, each with a different approach to generating sub-harmonics. Some are clean and clinical. Some are chaotic and experimental. One of them is a neural network. All of them will make your neighbours file a noise complaint about sounds they can’t technically prove exist.
The 12 engines
DDS (direct digital synthesis), Beat frequency, Additive, Frequency Division, Self-Oscillation, Neural (trained MLP), FM, Wavetable, Physical modelling (Karplus-Strong), Granular, Non-Linear, and Isochronic. Each one creates sub-harmonics differently — pick the flavour that fits.

Beyond bass
OwItHz isn’t just a bass plugin. It’s built on research into frequency-body interaction — 70+ cited sources in the research document. The therapy protocol editor lets you design frequency schedules with timed phases. OSC bio-feedback connects to external devices (heart rate monitors, EEG headbands) for responsive frequency adjustment. The visual flicker module implements the 40 Hz GENUS protocol for gamma entrainment.
This is experimental territory. We’re not making medical claims — we’re making tools and letting curious people explore.

Therapy protocols
Design timed frequency schedules with multiple phases — The Descent, Core Resonance, Integration. Each phase targets different frequencies, durations, and ramp curves. Six factory protocols included, or build your own.

The 3D sphere
Because every synth needs a good visualiser, and OwItHz has a Phong-lit OpenGL sphere that displaces its vertices based on the output frequency. It’s not useful. It’s mesmerising. Same thing.
Who it’s for
Bass music producers who want sub-harmonics that weren’t in the original. Sound healers and frequency researchers. Experimental musicians. People who own subwoofers that cost more than their car. Anyone who read “0.5 Hz” and thought “tell me more.”
