Voice → Zone Analyzer
Record or upload a sample, see how its acoustic energy distributes across the eight zones and how
that moves across the session, then log it with an intention for later comparison.

Which part should be analyzed?
Drag the handles to choose what gets analyzed. Nothing here detects which language is
being spoken — that is not something this tool can measure, and a guess dressed as a
measurement would be worse than none. It finds pauses, which are real and
measurable, and the shift into light language usually follows one. Where the boundary
actually goes is your call.
Half-speed playback shifts everything down one octave and takes twice as long to play.
It is the same transform the comparison below measures.
Measured
Frequency zone distribution
The relative distribution of this sample's energy across the eight analysis bands. Zone colors
follow the traditional chakra palette purely as a visual identifier — see the gold panel
at the bottom for what that framework does and does not claim.
A spectral measurement only: it describes where the sound's frequency content sits.
The bands overlap slightly at their edges and content outside 60–4000 Hz is not counted,
so these are proportions across the eight bands rather than a share of all energy in the
recording. No physiological or organ-level claim is implied.
Measured — across the session
Zone distribution over time
Each vertical slice is one time window, stacked to show the zone mix at that moment. A single
set of eight numbers averages a whole session flat; this is where the movement actually shows.
0:00
Hover anywhere on the strip to read the exact figures for that moment. Eight colors cannot all
be told apart reliably — Heart and Legs are the closest pair — so the readout, not the
color, is what identifies a zone.
Measured — comparison
Normal speed vs. half speed
Halving playback speed shifts all frequency content down by exactly one octave together. It
relocates where existing content lands on the zone map; it does not split content into new
destinations, and it adds no information the normal reading does not already contain.

Measured — generated geometry
Geometric synthesizer
A Lissajous figure: a parametric curve traced by combining sine waves at this sample's dominant
zone carrier frequencies (2D uses the top 2 zones by energy, 3D the top 3). Deterministic math
driven by your measured frequencies — not a simulation of a physical response, and not a
claim that sound carves these shapes into the body. Drag either figure to rotate it.
In the 3D figure each zone drives one axis, drawn faintly in its own color, and every segment
of the curve is colored for whichever zone’s axis it has traveled furthest along at that
point — so you can see which of the trio is shaping each part of it.
2D — dominant pair
3D — dominant trio
Measured — word valence
What was said
Type or paste what the speaker said. Scoring uses VADER, a lexicon method that accounts for
negation and intensifiers, so “I am not happy” scores negative. Every word that
carried valence is listed, so the number can be checked rather than trusted.
A lexicon score over the words only. It reflects the valence of the vocabulary used, not the
speaker's emotional state, their health, or the effect of anything they heard.

Every account, its consent state, and how much it has contributed.
By track
Counts and means only. The correlation view described in the brief is deliberately not built yet:
with a handful of samples and no per-speaker baselines it would produce a clean-looking chart of
noise. It needs both tracks carrying real data, and baselines, before it means anything.
Analysis versions in the data
Results are only comparable within one analysis version. If more than one version appears here,
samples across versions must not be pooled without re-analysis.

Everything below is computed from the samples currently loaded. Every figure carries its sample
size, and anything resting on too few samples is marked provisional rather than presented as a finding.

Traditional framework — not a measured claim
Chakra zone correspondences
These organ and emotional associations, and the zone colors used throughout this tool, come from
traditional chakra teaching — not from acoustic or physiological measurement. No result above
implies a zone's organs or emotions are being affected. Audio Hz and light color are also
physically unrelated units, so the color-coding is a visual label, not a frequency correspondence.
Feet and Legs are not part of the traditional seven-chakra system; they are an extension for this
eight-zone actuator layout.
Presented as tradition and experiential design language. No Hz value on this page has been shown
to cause a specific organ or emotional effect.

Deleting sends a confirmation link to your address; nothing is removed until you use it. It then
permanently removes your account, every sample you have saved, and any raw recordings you chose to
keep. The record that you accepted or declined the consent form is kept, because that record is the
only proof you were asked properly.
