Newbie mistake: I posted this yesterday in the wrong forum. I don’t know how to move it so I’m re-posting it here in the technical forum.

I bought a Uniden SDS200 scanner a few months ago and have been exploring its capabilities. As a retired software developer I thought it would be fun to write my own app to harvest and play the wav files stored in the scanner’s Micro SD card. I know other developers have already done this, including the authors of Proscan and USAP, but I’d rather learn how things work under-the-hood by reverse engineering the Uniden wav file format.

The enclosed pdf file describes what I’ve discovered so far. If anyone has any additional info on the Uniden wav file format I’d love to hear from you. I’m particularly interested in decoding the binary parts of the Uniden “unid” tag buffer.
