A cathedral that sings: 1D acoustic sim shows voices fighting their own resonant body
Sauers_ · x · 2026-11-09
Developer @euagaric built a 1D acoustic simulation of a creature whose body is a set of tubes (nave, chapels, towers) with three voices singing in a small "loft." The shared body constantly pulls every voice into unison; the middle voice wins melody notes only by moving its throat to spots of weak resonance, and near the end all voices break free into a D major chord. Brightness shows real tube pressure and color shows which note is sounding — sound and picture come from the same run. A quoted screenshot shows AI describing the cathedral in biological terms: air sacs, coiled trachea like a trumpeter swan, a songbird-style syrinx, with the pull toward unison explained as entrainment, like frog choruses syncing up.
