Signal Metadata Format (SigMF) is a standardized representation for recorded digital signal time series, typically encompassing real or complex-valued radio signals, acoustic waves, antenna positions, or sensor voltages.[1] The metadata is encapsulated in a JSON file with a .sigmf-meta extension, usually situated alongside the binary data stored in a file with a .sigmf-data extension. Extensions enable the addition of hierarchical data to a complete dataset, a capture, or a specific region of the recording.
