[FEATURE] Change the I/Q sample format for the rawfile output to a more standard one about rtlsdr-airband HOT 2 CLOSED

The rawfile output is a dump of the internal data structure with no additional processing.

I'm not familiar with 48k/1 wav files, but if the 48k is referring to the sample rate, that will require upsampling, and I dont think it makes sense to do that in rtl_airband.

Instead you can use sox to convert the output .cf32 files to any format you want. Looking at the man pages, this command may be what you're looking for (and if so please let me know and I'll add to the wiki):

sox −r 16k −e float −b 32 -L −c 2 input.raw output.wav

from rtlsdr-airband.

Hm, interesting. soxi reports the expected format for the samples - 32-bit Floating Point PCM, however, when i loaded the output wav file in GQRX and other software that accepts it, it fails to work with it.

During conversion, sox reports:

sox WARN sox: `input.raw' input clipped 2906524 samples
sox WARN sox: `output.wav' output clipped 1454773 samples; decrease volume?
