[Discuss-gnuradio] GQRX raw IQ file format / structure ?
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 ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

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

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 On 13/08/15 19:28, Chris Kuethe wrote: > cf32, pairs of 32-bit floats representing I and Q.
