In this video, I show you the simplest way to convert IQ files into SigMF format using GNU Radio.

You will learn how to:

✔ Load any .iq file (real or simulated)
✔ Use SigMF File Sink to generate .sigmf-data and .sigmf-meta
✔ Create a minimal valid SigMF file for signal analysis, AI/ML datasets, or SDR projects
✔ Work entirely within GNU Radio — no extra scripts required

This method works for:
SDR recordings
Simulated signals
Reverse engineering projects
AI/ML signal datasets

📁 What You Get
myrecording.sigmf-data → Raw IQ samples
myrecording.sigmf-meta → Minimal metadata automatically generated

🛠️ Tools Used

GNU Radio 3.x (qtgui optional)
SigMF File Sink block
IQ recordings (complex float32, cf32)

🔹 Perfect For:
SDR beginners
RF signal analysis
Wireless protocol datasets
AI/ML researchers using SigMF
