GR_READ_FILE_METADATA(1)

✨ NAME ✨

okay so bestie, welcome to the User Commands manual page for gr_read_file_metadata — and yes, it's a Gnu Radio Utility. 💅

💖 DESCRIPTION 💖

This one is simple in the best way: it reads in a GNU Radio file with meta data, extracts the header, and prints it. periodt. 🫶

Metadata file source and sink blocks — shoutout Tom Rondeau. 👑

So here's the tea: two new blocks implement enhanced file source and sink blocks, and those blocks incorporate metadata passed using the stream tags feature in GNU Radio. 🌈

Which means — and this is the iconic part — it is now possible to store things like frequency and sample rate into capture files, or literally whatever key/value pairs you tag onto data streams inside a flowgraph. no cap. ✨
