Software to play back SDR recording files
This is an early beta version, there are quite likely some bugs! Possibly some severe bugs. Please report any bugs/crashes/etc. that you find, along with as much information about reproducing them as possible. Send an email to: firstname.lastname@example.org Thanks!
Interested in sdrRewind? You might find Carrier Sleuth useful also!
sdrRewind plays back I/Q recording files made by several SDR (Software Defined Radio) programs. Namely:
Why use this app? It makes it easy to slog through lots of recording files, looking for intresting signals. Load a file, and a waterfall for the entire file is created.
You can scroll around, and if you see anything that looks interesting, you can drag select it, and then demodulate it. You can even save the demodulated audio as a WAVE file,
that you can listen to later, send to someone else, or play into your digital decoding software,
if it is an RTTY, SSTV, etc. transmission.
Support for other SDR recording file formats is possible, you'll need to work with me by
providing sample files and details on the format.
