It looks very suspect. Like it should be multiplied or divided or something instead of the first value assigned to d0sq just being discarded.

Thanks for pointing out problematic code. Sorry when I uploaded the revised dll in May I missed to upload the updated source. I have done that now. Yes instead of the included lte file
the official fftw3 header can be used, but I found it to be so difficult to understand started using Fizik's lte version with suitable modifications.
As regards numerous warnings, yes I am guilty and lazy. Thankful for correcting.
