Make sure you have a throttle block between the source and the FFT, set
to the rate at which you captured the wav. Also, there is a Wav File
Source under Audio. The plain File Source will also work (usually WAV is
16-bit signed, 2 chan), but will have a little noise at the beginning
(the wav header).

Hi,
I have recorded with FCD pro+ and SRD# some IQ.wav files.
When I try to import them in Gnu Radio companion as a "File source" and
plot the frequency spectrum with the "FFt sink" I get nothing.
Are the IQ.wav files produced by the SDR# recognizable from the Gnu radio?
Thanks!
