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.
