Hi,
I've been playing with the fft/ifft a while, and I noticed that only half
of the tables (re and im) are being used. (For example, with a fft-size of
512, only the first 256 of the re and im tables are used.) I understand it,
but I don't see why the table size must then be the same as the fft/ifft
size. Shouldn't it be more logic to require half the fft-size as the
table-sizes?
Also, must the fft-size be a power of two? In the reference implementation
it gives a runtime error if it is not a power of two, but on the other hand
there are functions provided for if fftsize is not a power of two.
Thanks,
Niels Gorisse
