## What it is
SDR++ is a cross-platform, open-source software-defined radio (SDR) application designed to be bloat-free and simple to use. It supports a wide range of SDR hardware via SoapySDR and dedicated modules, with SIMD-accelerated DSP and a modular plugin architecture.

## Use cases
- listen to radio signals from an RTL-SDR dongle
- browse the spectrum with a waterfall display
- decode radio transmissions on multiple frequencies at once
- use my SDR hardware on Windows, Linux, and macOS
- write custom plugins for my software-defined radio
- monitor air traffic or amateur radio bands
- visualize RF signals in real time

## When to choose
- you want a lightweight, fast SDR receiver with multi-VFO support
- you need broad hardware support across platforms including BSD
- you want to extend the software with your own C++ plugins
- you prefer open-source GPL software with active development

## When to avoid
- you need advanced decoding suites built in (use dedicated decoders alongside)
- you want a one-click package on less common Linux distros without building from source
- you need a web-based or remote-only SDR interface

## Facets
- artifact type: application
- maturity: active
- function: audio-processing, plugin-system, gui
- domain: hardware, cross-platform, developer-tools
- platform: windows, bsd, cpp
- tags: sdr, software-defined-radio, dsp, radio-scanning, waterfall-display, soapysdr, linux, macos
