PHONOS
the domain of SOUND ITSELF: the physics and lineage of the pressure wave.
14 modes · the plate sings · sealed & live
Two-layer honest: the acoustics and every synthesized patch are LIT (real ratios, real math, fail-loud self-tests); the analog-Hawking and cochlea-as-wavelet readings and the Faraday-dust drift model are AMBER, flagged. Keeper: ERNST CHLADNI, the father of acoustics — the touring showman who made
