The IQ.wav file is indeed 16-bit signed, 2 channels, but it has sample
rate=192000 (FCDpro+)
I want to get the Complex output (Audio output is always Float).
My setup is: fileSource -----> Throttle ------>wx fft sink.
Still get nothing

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!
