sdrRewind

Software to play back SDR recording files

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:

• Perseus
• SdrDx
• SDR#
• SDRuno
• SpectraVue
• Studio1 / SDRUno
• ELAD SW2
• Sdr-Radio/Console - Sometimes works, the files format unfortunately often changes, causing problems.
• HDSDR
• KiwiSDR I/Q files from browser
• LinRad

Why use this app? It makes it easy to slog through lots of recording files, looking for interesting 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.

You can also make long waterfalls from multiple I/Q files, this example shows one that I later went back and annotated, click to view full size:

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.
