SONIFICATION PROFILE

Canonical identity first, receiver sound second.

ETQ-101 supplies the reversible symbolic code: M(m,q) = 14 + 33q + m, with fixed singlets at MIDI notes 13 and 113. This lab then declares a separate e8-geometry-auditory-display-v1 receiver: root family shapes partials, selected-graph degree shapes brightness, Coxeter ring shapes spectral colour, qutrit label shapes pan, and the SCL value shapes phase modulation. Tempo, A4, gain, timbre, PCM, and WAV are recorded receiver settings—not E8-derived constants.

q = 0 MIDI 14–46 · low lane · SCL +1 q = 1 MIDI 47–79 · mid lane · SCL −2 q = 2 MIDI 80–112 · high lane · SCL +1

INTERPRETATION BOUNDARY

Exact E8 mathematics; authored projection and auditory display.

The 240 roots, inner products, 6,720 graph edges, Coxeter element, 8×30 ring structure, embedded order-three D4 triality, and ETQ-101 selector are reproducible mathematical constructions. The exponent-7 depth axis, screen perspective, traversal order, low/mid/high display polarity, receiver tuning, waveform, loudness, timbre and WAV realization are declared design choices. They do not establish a preferred physical frequency, a 101-dimensional E8 representation, or an acoustic law of E8.
