Every sound has
a tone, an attack, a soul

HodgeCodec splits any track into three real, separately-playable layers — and reconstructs them losslessly. No magic. Exact decomposition, hardware-accelerated.

Hear it split apart.

Real decomposition running in WebAssembly — powered by AFA bisimulation-driven bitrate allocators and topological noise cancellation.

The concept

Three layers. One file.

The split is mathematically unique — every sound decomposes into exactly one set of these three layers, and they sum back to the original exactly.

∇φ

TONE

The melodic tendency — where the sound wants to go. Pitch and structure, stripped of hits and noise.

δψ

ATTACK

The rotational energy. Drum hits, string plucks, percussive transients — isolated cleanly.

h

SOUL

The invariant core that's neither tone nor attack — a fingerprint unique to every recording.

Fidelity

Numbers.

Prophet-6 synthesizer, 383s, 48 kHz. Same file size class, higher fidelity. Optimized for S23+ (Snapdragon 8 Gen 2) and Apple M1–M3.
