The Signal Metadata Format (SigMF) specifies a way to describe sets of recorded digital signal samples with metadata written in JSON. SigMF can be used to describe general information about a collection of samples, the characteristics of the system that generated the samples, and features of the signal itself. It is designed to be a simple and portable format that is easily used by memory-limited applications with real-time requirements and minimal dependencies.
