Based on different fft-sizes I am getting u0u0u0u0 output.
The strange thing is an "unregular" fft-size of 1088 doesnt produce
the error but fft-size 1024 does
also a smaller fft-size of 544 does produce the error.
So what is causing this kind of error and which approaches can I use
to debug this?
What type of sample rates? What compute platform?
FFTW performance is often counter-intuitive.
Are you using the default TPB scheduling?
What else is in your flow-graph?
