Expand description
Phenomenal U2/U3 spectral parity — shared σ truth for vision and AcousticPlane (P-F2).
Visual: portal_spectral::sigma_to_cie_xyz / spectral.wgsl (λ ≈ 400–700 nm).
Audio: sigma_to_center_frequency_hz folds the same λ band into audible Hz for parametric synth.
Constants§
- ACOUSTIC_
UNIFORM_ FLOAT_ COUNT - ACOUSTIC_
UNIFORM_ SCALAR_ COUNT - Flat uniform scalar count pushed to AudioWorklet (
acoustic_uniform_floats).
Functions§
- phenomenal_
acoustic_ params - Build phenomenal acoustic params — σ oracle drives frequency; preview bins carry tensor lerp.
- phenomenal_
fm_ index - phenomenal_
voice_ frequency_ hz - Frequency + FM for worklet — uses phenomenal σ mapping (not bin peak alone).
- sigma_
to_ center_ frequency_ hz - Phenomenal audio twin: map σ → center frequency (Hz) for parametric voice.
- sigma_
to_ wavelength_ nm - Wavelength (nm) — must stay aligned with
portal_spectral::sigma_to_cie_xyz.
