Put your own voice in. Watch it become its pattern. Hear it returned to you — your voice, clear as day; your tones; and a dial to tune with. A Jelkal work in progress. Your voice never leaves your telephone: every measurement happens right here, on this device.
1 · YOUR VOICE, IN
No voice yet. Record a few seconds — a verse, your name, anything — or load a voice note.

YOUR VOICE IN NOTES
Not only the wave — the music. The notes your voice sang, written on the staff. Your root note stands in gold.
Record your voice above, and your notes will stand here.
3 · YOUR VOICE, RETURNED
Three reflections of the same voice: itself, its tones, and the dial.

5 · YOUR COLOUR — THE OCTAVE LADDER
Every note climbs by doubling. Double a sound's frequency about forty times and it leaves the ear and enters the eye — sound's highest octaves are colours. Newton divided his rainbow into seven colours to mirror the seven notes of the scale. Here is your voice on that ladder: your root, its octaves, and the colour your root lands on.
The chart above is the reference map (the Hawkins scale, labelled in the chart as a scale of consciousness — a map, not a lab measurement). Your colour below is computed from your own voice by octave arithmetic: your root frequency, doubled into the visible band. A correspondence, drawn honestly — not a diagnosis.
Voice Spectrum Analysis (VSA) is an exploratory instrument for meeting your own voice as pattern and tone. It is not a medical device, and it diagnoses or treats nothing — it listens, it measures, it reflects.
Built October 23, 2026, from the test trials of October 22–23: voice → pattern → voice → words, and voice → tones. All rights belong to Jelah (Jelkal). Version 1.1 — the Colour Room (the octave ladder) added October 23, 2026. Version 1.2 — the dial gains fine steps (−10, −1, +1, +10) and an exact-number box, at Jelah's word the same morning. Version 1.3 — YOUR VOICE IN NOTES: the voice written in musical notation on a staff, the root in gold, at Jelah's word the same morning. Version 1.4 — the dial's note stands on its own staff in section 4, at Jelah's word the same morning (rendering corrected the same morning).
