SPECTRALBINARY·THE FRAMEWORK
Most AI reads language.
ToneThread reads tone.
SpectralBinary is a deterministic, five-axis tonal signal framework. It does not classify sentiment. It does not require training data. It maps any piece of text to a precise coordinate in tonal space — reproducibly, every time.
The problem with positive, negative, neutral
Standard sentiment analysis collapses everything to a single dimension. Positive. Negative. Neutral. Useless for anything that requires nuance.
Two messages can score identically positive — one written with warmth and genuine certainty, another with cold precision and veiled pressure. Standard sentiment cannot tell them apart. A neurodivergent reader processing the second message may not articulate why it feels wrong — they just know it does.
SpectralBinary makes the difference visible. Not as a label. As a coordinate.
The five axes
Every piece of text produces five normalised scores between 0.00 and 0.99. Together they form a tonal fingerprint — a five-dimensional coordinate that uniquely describes the signal.
Warmth
The relational temperature of the text. How much empathy, connection, and care is structurally present.
Certainty
The epistemic confidence in the language. High Certainty is decisive; low Certainty hedges and qualifies.
Intensity
The energy and urgency of the signal. Magnitude — how much it pushes, insists, demands attention.
Coherence
The structural integrity of the tonal trajectory. Does the signal hold together across the text?
Resonance
The temporal persistence of the signal. How much of the current tone carries weight from what came before.
How it works
SpectralBinary operates at the character level. Each character maps to a fixed value on a normalised continuum. Sequential composition produces a tonal trajectory across the text.
A Recursive Momentum Operator smooths that trajectory.
Deterministic. Auditable. IP-defensible. Suitable as a cryptographic component in ToneHash certificates.
ToneHash: tonal fingerprints in the certificate
Every post receives a ToneHash certificate. It binds a SHA-256 content hash with the SpectralBinary fingerprint at the moment of publication — a signed, tamper-evident record of both what was written and what it sounded like.
