HodgeCodec splits any track into three real, separately-playable layers — and reconstructs them losslessly. Optimized with ARM NEON for Apple Silicon & S23+ with H^1 Cohomology Phase-Lock.
Real decomposition running in WebAssembly — now powered by AFA bisimulation-driven bitrate allocators and topological noise cancellation.
The split is mathematically unique — every sound decomposes into exactly one set of these three layers, and they sum back to the original exactly.
The melodic tendency — where the sound wants to go. Pitch and structure, stripped of hits and noise.
The rotational energy. Drum hits, string plucks, percussive transients — isolated cleanly.
The invariant core that's neither tone nor attack — a fingerprint unique to every recording.
Prophet-6 synthesizer, 383s, 48 kHz. Same file size class, higher fidelity. Optimized for S23+ (Snapdragon 8 Gen 2) and Apple M1-M3.
