designing arf, an sdr iq encoding format 🐶

I'll be maintaining ARF going forward at /draft-tagliamonte-arf-00.txt. It’s true – processing data from software defined radios can be a bit complex 👈😏👈 – which tends to keep all but the most grizzled experts and bravest souls from playing with it. While I wouldn’t describe myself as either, I will say that I’ve stuck with it for longer than most would have expected of me. One of the biggest takeaways I have from my adventures with software defined radio is that there’s a lot of cool crossover opportunity between RF and nearly every other field of engineering. Fairly early on, I decided on a very light metadata scheme to track SDR captures, called rfcap. rfcap has withstood my test of time, and I can go back to even my earliest captures and still make sense of what they are – IQ format, capture frequencies, sample rates, etc. A…
