eti-cmdline-rawfiles and *.sdr support #16

Closed andimik closed 7 years ago

andimik commented 7 years ago

As qt-dab saves dumps as *.sdr (s16le resp s16be), why not add support for it in eti-cmdline?

JvanKatwijk commented 7 years ago

I'll look into it. The obvious next question then will be: "why can't you read in ".sdr" files"

You could give eti-cmdline a try, I added both a dumping facility (add -DDUMPING=ON to the cmake command) and a WAV file option for reading ".sdr" files

I ran a few tests and it seems to work

No. Seg fault :-( I've tested around 10 different sdr files.

eti-cmdline-rawfiles work, indeed.

The sdr was generated with Airspy.

Strange, works like charm here

The thing I have to address now is to gracefully terminate after reaching eof with both raw and wav files

Thanks for the new version, works now. :-)

I have a very weak recording from a signal around 200 km away, sdr is the only format where I have audio. As soon as I convert it into 8 bit raw, the SNR is too poor for any tool.

That's why this new version is like a present for me.

good to hear
