SDR++, The bloat-free SDR software.

SDR++ is a cross-platform and open source SDR software with the aim of being bloat free and simple to use.

Current Features

• Uses SoapySDR for wide hardware support
• Hardware accelerated graphics (OpenGL + ImGui)
• SIMD accelerated DSP (parts of the DSP are still missing)
• Cross-platform
• Full waterfall update when possible. Makes browsing signals easier and more pleasant

Comming soon

• Multi-VFO
• Plugins
• Digital demodulators and decoders
• Quick replay (replay last n seconds, cool if you missed a short signal)

Small things to add

• Switchable bandwidth for demodulators
• Switchable audio output device and sample rate
• Recording
• Light theme (I know you weirdos exist lol)
• Waterfall color scheme editor
• Switchable fft size
• Bias-T enable/disable
• other small customisation options
• Save waterfall and demod settings between sessions
• "Hide sidebar" option
• Input filter bandwidth option

Known issues (please check before reporting)

• Random crashes (yikes)
• Gains aren't stepped
• The default gains might contain a bogus value before being adjusted
• Clicks in the audio
• In some cases, it takes a long time to select a device (RTL-SDR in perticular)
• Min and Max buttons can get unachievable values (eg. min > max or min = max);
