Main features: multi-VFO, modular architecture with plugin support, all common DSP features with SIMD-acceleration, fully functional waterfall and support for multiple platforms (Windows, Linux, macOS and BSD).
Hardware support: SDR++ works through SoapySDR (and also through some dedicated modules), which allows it to work with a wide range of SDR devices (RTL-SDR, Airspy, SDRplay, PlutoSDR, etc.).
License and download: the project is licensed under GPL-3.0; you can find official packages and releases on GitHub Releases and the latest nightly builds on the project page (nightly builds). The documentation also includes compilation instructions for different OSes.
