There are some really nice tools out there for making use of SDR devices. I've personally been using gnuradio to get a better sense of how various modulation and filtering techniques work on real-world signals. Lately, however, I've been feeling the itch to dive more into the details and implement some of these techniques from scratch. In this article, I'll write a basic FM demodulator in C that can be used to listen to FM radio from an RTLSDR device.

I rewrote the Color Quantization algorithm from last time into a Bun application, a C++ application, and a multithreaded C++ application to improve performance.
