CubicSDR die SDR-Software für den Mac, Windows und Linux

CubicSDR ist die erste für mich ernsthaft zu nutzende SDR-Software unter dem MAC Betriebssystem OSX. CubicSDR läuft tatsächlich – unter anderem – unter plain OSX und nicht in irgendeiner Emulation wie z. B. Wine, VMware oder sonstige.

Ich nutze es in letzter Zeit immer häufiger mit meinem SDRPlay.

Die Software befindet sich allerdings noch in der alpha Phase und wird ständig weiter entwickelt. Die Homepage von CubicSDR findet man hier.

Wer der Entwicklung folgen möchte, oder sogar daran teilnehmen will, sollte mal auf Github gucken. Dort finden Diskussionen zu der Software statt und man findet dort auch immer die aktuellsten Versionen und Informationen.

Demnächst soll es auch möglich sein, Digital Modes mit CubicSDR darzustellen.

Hier noch die derzeitige Features und Status Liste von CubicSDR:

  •  Group and divide IQ data distribution workload instead of 100% distribution per instance

Advanced Goals and ideas:

• Design a plan for expansion via modules (dylib/dll/lua)
• Support shell-based stdin/stdout tools for direct output/playback to/from CLI audio processing apps (i.e. DSD on OSX)
• Update visuals to support OpenGL ES
• Basic demodulator filter(s) that can be enabled and tweaked visually
• Support multiple simultaneous device usage
  • Categorize devices by antenna connections
  • Allow locked frequencies to activate unused devices to continue demodulation on same antenna
• Integrate LUA
  • Expose liquid-dsp functionality
  • Scriptable liquid-dsp demodulation
  • Scriptable digital demodulation output handlers
    • Create block output devices on *nix?
    • Create socket outputs?
    • Visual outputs?
  • Take control of additional devices and spawning new demodulators (i.e. trunkers)
  • Script manager / live editor
  • Provide scriptable liquid-dsp modulation for transceivers?
  • Allow scripts to launch/run headless (no UI)
• „PVR“ like mode with waterfall time shifting
• L/R and surround-sound balance settings for separating and listening to mono streams
• Add tool for converting decimated I/Q recording to video
  • Select video features such as title/demodulation/scope/waterfall/etc.
  • Render to video from GL frames->ffmpeg/mencoder /w demodulated audio
• Accessibility / Control
  • USB/MIDI control surfaces
  • Joystick / gamepad input
  • Vibration / force-feeback
• Investigate compilation via emscripten using SoapyRemote for input
  • Create web server+SoapyRemote bundle for embedded devices
