CubicSDR
CubicSDR is a free, open-source software-defined radio (SDR) application that enables users to tune, visualize and decode radio signals across a wide frequency spectrum. It supports various SDR hardware platforms including RTL-SDR dongles, Airspy, and others, allowing radio enthusiasts, researchers and professionals to receive and analyze FM, AM, SSB, digital modes and other broadcast signals. The app includes a waterfall display for real-time frequency analysis, multi-threaded signal processing, and the ability to listen to and record decoded audio. CubicSDR is cross-platform, with community-maintained builds for macOS, Windows and Linux.
AI Recommendation
1 suggestionCubicSDR is an open-source project maintained on GitHub, and the macOS build has not yet shipped a native Apple Silicon version by default. Community discussions from early 2024 confirm that users have asked the developers about Apple Silicon support, but no official native build has been released. The app continues to run under Rosetta 2 on M-series Macs today, but Apple is removing Rosetta in macOS 28 (September 2028), so an Intel-only build will stop working at that point. Watch the CubicSDR GitHub releases page (github.com/cjcliffe/CubicSDR) periodically for news of a native Apple Silicon build. If you rely on CubicSDR, reach out to the project maintainers directly to express interest in Apple Silicon support — active user demand can help prioritize the effort. As a contingency, you may also explore SDR Trunk, a Java-based SDR application with confirmed native Apple Silicon support, though it has a different feature set and user interface.
