You need an ishort-to-complex block after the file source. The file
source does not convert for you. If that doesn't work and your data is
definitely good (and not too short), then no idea.
Please send replies to the list.

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!
