[Discuss-gnuradio] GQRX raw IQ file format / structure ?

2015-08-13 Thread M Dammer
GQRX has a built-in I/Q recorder (tools menu) to save raw I/Q files. I
would like to process these files with Python and other signal
processing software. Does anybody know the exact format and structure of
these files ? I am only aware of the filename in the format
gqrx_DATE_TIME_FREQ_SAMPLERATE_DEVICE.raw
tnx, Mark

cf32, pairs of 32-bit floats representing I and Q. GnuRadio's file
source can read these directly.

GDB has a 'break' feature; why doesn't it have 'fix' too?

Thanks for the quick reply. I tried to use sox to convert the files into
WAV files to read into other software and it worked fine:
sox -t raw -e floating-point -b 32 -c 2 -r 192000
./gqrx_20150812_193915_113821000_192000_fc.raw  test.wav
