CubicSDR0.2.5

CubicSDR lets you use a Mac to explore radio signals through software-defined radio, turning received broadcasts into an interactive visual and listening experience. Its spectrum display shows activity across a selected portion of the airwaves, while the waterfall view reveals how signals change over time. You can tune individual signals, adjust reception settings, and listen to supported transmissions through the application’s audio output.

The program is suited to radio hobbyists, experimenters, and learners who want to inspect live radio activity rather than rely on a conventional hardware interface alone. It can be used for browsing local broadcasts, examining signal behavior, and learning how frequency, bandwidth, and modulation affect reception. CubicSDR’s cross-platform design also makes its interface familiar across supported desktop environments, while this edition is built for MacOS.

Version 0.2.5 runs on both Intel and Apple Silicon Macs. CubicSDR is freeware, so its stated license does not impose a paid license requirement. As a Music & Audio program, it combines radio-frequency visualization with practical audio monitoring in one desktop workspace.
