HelioSynth turns harmonic proportion, vibration, rhythm, acoustics, and generative composition into instruments that can be seen, heard, and tested directly in the browser.
Begin with two small signal studies, then continue into the Still Chamber meditation system. Audio remains silent until you review the listening terms and deliberately unlock it; no microphone, account, tracking system, or download is required.

01 / A public acoustic laboratory
A signal,
an instrument,
an exhibit.
HelioSynth is a browser-based acoustic exhibit for experiencing proportion, interference, pulse, breath, and generative sound as visible and audible relationships.
This first public sequence is intentionally focused. Change a whole-number interval, watch its curve close, then build a Pythagorean layer from octave-folded fifths before carrying those relationships into the Still Chamber for a longer listening session.
Number becomes interval. Interval becomes rhythm. Rhythm becomes architecture.
Listening safety / Use acknowledgment
Pause before
you press play.
HelioSynth uses repeated tones, rhythmic pulses, stereo differences, visual motion, and paced-breathing cues. Review these conditions before unlocking any audio exhibit.
- Start below 60% device volume in a quiet, safe, stationary setting. Never use these exhibits while driving, cycling, or operating equipment.
- Stop immediately if you experience discomfort, dizziness, nausea, anxiety, headache, ringing or pressure in the ears, visual strain, or any unusual symptom.
- If you have epilepsy or a seizure history, sensitivity to repetitive sound or visual patterns, tinnitus, hyperacusis, or a neurological condition, seek guidance from a qualified clinician before use.
- HelioSynth is a creative and educational instrument—not a medical device or medical care—and does not diagnose, treat, cure, or prevent any condition.
Audio is locked. The visual exhibits remain available.
02 / Signal primer · Two interactive studies
Touch the
first principles.
These compact exhibits approach harmonic proportion in two ways: first as a single interval, then as a layered field generated from the pure 3:2 fifth.
Use a comfortable volume. Each exhibit stops the other before it begins, and all primer sound stops when this page is hidden or closed.
The Pythagorean Layer
Build a sounding field from ratios generated by the pure 3:2 fifth. Every selected degree joins the 216 Hz root.

03 / Featured instrument · Meditation Engine 006
The Still
Chamber.
A binaural-beat, isochronic-tone, drone, noise-bed, and breath-pacing instrument. Choose a quiet carrier, pulse rate, scene, and session length; the sound is generated locally on the visitor’s device.
- Binaural, isochronic, or combined modes
- Deep drone, hum, Pythagorean ratio, tide, and colored-noise layers
- Breath guide and timed meditation scenes
Session note.Binaural mode requires stereo headphones; isochronic mode works through speakers. The listening acknowledgment above must be accepted before the chamber loads.
