As you expected, disabling buffering on the file sink did not have any
effect. I have fixed the issue though by making two changes to

1) change scale_factor to 32768 (1/2^14 doesn't make sense, it causes

Thanks for the quick reply!
When I said splitting in the GUI I meant using the flowgraph (instead of
digging into the code) not using the sink FFT. As you say, I am using
the standalone block for the FFT and I want to split its output. Is
there any block to do so or any kind of snippet of

Thanks for the FOSDEM 14 video on youtube (although maybe not posted by

Hi Zamrath,
your questions become very specific to your system, and can't easily be
answered by just reading the error texts. You will have to investigate a
bit deeper yourself and at least find out in which context (sub-step)
these things occur.

Hi Merry,
the taps characterize the channel you want to simulate, so you will need
to calculate these based on your mathematical channel model. The
classical multipath channel model is a tapped-delay line-model, and that
kind of directly maps to the concept of filter taps.
Are you sure you do 4

Thanks for your very detailed comments.
