Charles J. Cliffe 9d9bb8f103 OSX .app compiles but with runtime dylib errors 
Regular binary compilation works, manual wxWidgets compile required for
app (port version doesn’t work for me).
Fixed-up app has runtime errors with dylib files but otherwise verifies…

CubicSDR

Cross-Platform Software-Defined Radio Application

Utilizes:

Basic Goals and Status:

  • Simple UI
  • Devices
    • RTL-SDR
    • rtl_tcp
    • HackRF
    • Whatever else I can get my hands on
  • Minimal configuration
    • Device Selection
    • Bandwidth
    • Color scheme
    • Load/Save session
    • Default audio device and settings / preferences
  • Neat Visuals
    • Scope
    • Spectrum
    • Waterfall
    • Audio Spectrum
    • More 2D visuals
      • Add faint grid for sense of scale
      • Indicate outer spectrum edges when zoomed
    • 3D visuals
  • Demodulation:
    • Design a proper architecture for modular expansion :)
    • Multiple demodulators per IQ stream
    • Audio device selection
    • Modes
      • FM
      • FM stereo
      • AM
      • LSB
      • USB
      • DSB
      • RAW
    • Controls
      • Display Frequency and allow manual adjustments
      • Allow selection of demodulation type
      • Display separate zoomed-in view of current waterfall and spectrum, allow adjustments
      • Display signal level and allow squelch control
      • Display audio output selection
      • Volume control
      • Demodulator input filtering
      • Audio filtering
  • Basic Input Controls
    • Drag spectrum to change center frequency
    • Hold shift and click on waterfall to create a new demodulator
    • Clicking waterfall adds new demodulator when none visible
    • Drag center of demodulator on waterfall to change frequency
    • Drag edge of demodulator on waterfall to change bandwidth
    • Double-Click to move demodulator to frequency within it's current range
    • Hold alt and drag range on waterfall to set demodulator frequency + bandwidth
    • Hold alt+shift and drag range on waterfall for a new demodulator
    • Hover demodulator on waterfall and press 's' to toggle squelch
    • Hover demodulator on waterfall and press 'space' to toggle stereo
    • Hover demodulator on waterfall and press 'd' or 'delete' to delete it
    • Keyboard arrows adjust frequency, shift for faster change
    • Undo / Redo action
  • IQ Recording and playback
    • Recording
    • Playback
  • Audio
    • Recording
  • Optimization
    • Eliminate large waterfall texture uploads
    • Update visuals to OpenGL 3.x
    • Resolve constant refresh on visuals that don't change often
    • Resolve driver/platform vertical sync issues
    • Group and divide IQ data distribution workload instead of 100% distribution per instance

Advanced Goals:

  • 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
  • Implement digital demodulation supported by liquid-dsp: (http://liquidsdr.org/doc/modem.html)
    • PSK, DPSK, ASK, QAM, APSK, BPSK, QPSK, OOK, SQAM, Star Modem(?)
  • 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 trancievers?
  • "PVR" like mode with waterfall time shifting
  • L/R and surround-sound balance settings for separating and listening to mono streams

Target Platforms:

  • OSX
  • Windows
  • Linux
