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?
