📔 radio-core

Python based DSP for CyberRadio and PyRadio.

Accelerated on the GPU with CUDA by #cuSignal.

Features

Analog

• WBFM: Demodulation of wideband FM stations with Stereo Support. Supports 75uS and 50uS de-emphasis.
• MFM: Demodulation of wideband FM stations without Stereo Support. Supports 75uS and 50uS de-emphasis.

Tools

• PLL: Custom implementation of clock-recovery and phase estimation for real signals.
• Tuner: Fast combo-tuning of wideband signals using FFT, IFFT, and polyphase-decimation.

Installation

$ pip3 install git+https://github.com/luigifreitas/radio-core.git

Hacking

If you are interested in the core DSP, you are in the right place! If you want to tinker with the code and make your own application, you should look for the PyAudio Repository. If you just want to use to listen to some good music, try the CyberRadio Desktop App.

Roadmap

This is a list of unfinished tasks that I pretend to pursue soon. Pull requests are more than welcome!

• Improving documentation.
• Fix Tuner decimation for lists with varying sample-rates.
• Implement RDS Decoder.
• Deploy on PIP.
