Cedron,I believe your mathematical prowess will not be debated here.  Next time I need a window function, I will explore the efficacy of a zeroing sine window. ...
The actual problem with the code given is use of the unwrap() function.  This is not needed nor appropriate for the results of an FFT across bins. unwrap() is...
There are multiple problems with the implementation. Your need to scale the floating point coefficients so as to represent them as 16 bit integers.    Scaling...
The code does not show variable types or initialization values.  I assume your x and z buffers are sized accordingly (2N).  To my knowledge, the C5545 is a fixed...
