SDR++

SDR++ is a free, open-source software-defined radio application designed for receiving and analyzing radio signals through compatible SDR hardware. It provides a lightweight interface for tuning frequencies, viewing spectrum activity, and demodulating transmissions. The application supports multiple virtual frequency oscillators, allowing users to monitor several signals within an available bandwidth. Its hardware compatibility includes dedicated receiver modules and devices supported through SoapySDR. SDR++ uses SIMD-accelerated digital signal processing for efficient signal handling. Its waterfall display provides detailed visualization of radio activity over time. Available for Windows, macOS, Linux, and BSD, it features a modular architecture that allows developers to extend functionality through plugins.
