Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does

Backed by real-time spectral, loudness, dynamics, stereo, and phase analysis via the Phantom MCP server. 5 domain expert skills work together as a complete audio production pipeline: analyze first, set up the DAW, mix with measurement-backed decisions, add creative effects, and master to streaming specs.
Audionaut
Edit Audionaut multitrack audio projects: cut, arrange, fade, analyse, auto-edit, export
