Your track has a diagnosis.
Not just a volume knob.

See how our system works.

Two minutes, unscripted — the ten-zone diagnosis, the treat-only-the-sick mastering, the cymatic plates, live. Not a mockup: this is the actual tool, patent pending U.S. application no. 64/132,904.

◉ Live capture of the real tool — the ten-plate cymatic view reading a track. Want the full walkthrough with sound? Watch the 2-minute demo (59 MB — heavy on slow connections).

Every recording has a signature. Aberrations the ear pays for — and generic mastering doesn't see.

AI-generated, hybrid, or fully human — every production carries its own aberrations. Scanned closely, they resolve into artifacts that interfere with the regions where human hearing lives — and research associates energy in some bands with listening fatigue and hearing damage. Our filter system was developed from that science: find each artifact, treat it, bound the doses.

Seven plates. Every border is physiology, not a round number.

Your track's standing-wave patterns, drawn live per zone — voice floor at 250 Hz, the mud line at 700, the F1/F2 formant border at 1.2 k, the ear-canal resonance at 3.43 k. When a plate looks sick, the name of the plate is half the diagnosis.

Click any plate above to read its zone — example exam, the same track pictured in The Physics.

Example exam — the same track whose plates and report appear in The Physics section. Illustrative of how a report reads; your track gets its own measured numbers.

The algorithm, drawn. Why no two zones look alike.

Each zone is rendered as a Chladni plate — the physics of a vibrating surface, where a tone's frequency sets the pattern's complexity by the plate law f ∝ n²+m². Low frequencies can only draw a few sweeping curves; high frequencies force fine lattices. That's why BASS blooms like a star and AIR weaves a grid — the shapes aren't styled, they're computed.

Loud is easy to hear. Comfortable-for-an-hour is the hard part.

Most mastering optimizes for the first ten seconds — bright, loud, impressive on a phone speaker. What it doesn't measure is what happens by minute three: research on listening effort (Zekveld & Kramer, 2010) shows the brain works harder to process harsh, fatiguing energy, even when a listener can't consciously name why a track feels tiring. That's the problem this engine was built to see and treat — not by making tracks quieter, but by finding which specific band is doing the tiring, and bounding it.

Two plates, two different jobs. CLARITY carries intelligibility — vocals cutting through — and the engine lifts it freely. EDGE overlaps the published listener-aversion band and the frequency region associated with noise-exposure damage in the hearing-research literature, so correction there is bounded rather than pushed for impact. Same plate architecture the diagnosis screen shows you on every track — this isn't a separate "safety mode," it's the same engine, watching the same zones, every time.

Inaudible isn't the same as harmless.

Below 20 Hz and above 20 kHz sit outside the range human hearing evolved for — infrasound and ultrasound. Neither shows up as "sound" the way a listener would describe it. But a growing body of published research finds that exposure to both bands produces measurable effects even when nobody in the room can consciously hear a thing.

One instrument. Any signal with a spectrum.

The same architecture that diagnoses a song — anchored zones, per-zone detectors, harmonicity in cents, static-line physics, standing-wave figures — reads any ordered sound. Patent-pending across these domains.

Early-access domains ship under the Scientific Research tier — diagnosis and comparison reports only, no treatment applied. Compare two aircraft with the same engine, two hives, the same machine before and after service.

Two instruments. Paid members only.

Every account is a verified, subscribed member — no free tier, no anonymous traffic. Pick the instrument that matches your work.
