CuteSDR

The application provides a graphical interface for software‑defined radio receivers, offering real‑time spectrum visualization and demodulation of incoming signals. Built with Qt, it runs on macOS and presents controls for tuning, filtering, and audio output in a single window, allowing users to monitor and decode radio broadcasts without needing separate tools.

It is aimed at hobbyists and professionals who operate SDR hardware such as AFEDRI and CloudIQ devices, and it is noted for being straightforward to set up and fully functional out of the box. The author’s related projects, including SpectraVue, share a common code base of digital‑signal‑processing routines that are described as reliable, well‑commented, and easy to understand.

The software is released as open‑source, has a stable maturity level, and is maintained through SourceForge where users can access the code, report bugs, and receive updates.
