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
|
|
- 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
|
|
- Accessability / Control
|
|
- USB/MIDI control surfaces
|
|
- Joystick / gamepad input
|
|
- Vibration / force-feeback
|
|
|
|
|
