Diffusion
Diffusion Software is a small independent software vendor that develops audio-encoding and RDS (Radio Data System) tooling for FM radio broadcasters. Its flagship product, Airomate, is a software-based RDS/RBDS encoder that generates a high-quality RDS signal using a 192 kHz-capable soundcard, letting stations broadcast professional-looking RDS information (station name, RadioText, program service data) at low cost without dedicated hardware. The company also ships complementary broadcast utilities: StereoCoder (an FM stereo/MPX encoder), Little SineGen (a sine-wave generator that runs at any sample rate the soundcard supports), and Chronos (a free scheduler that sequences Programme Service name and RadioText messages for Airomate). The products are Windows desktop applications distributed as low-cost licensed downloads. Diffusion Software is a seed-stage Canaan Partners portfolio company and does not publish a public API, SDK, or developer portal; this profile is maintained as a network identity record.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Diffusion the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Diffusion scores 9.7/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Diffusion
Each block below is one kind of artifact we hold for Diffusion. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
