#X text 163 24 The [fft~] object has separate inlets for the real and
imaginary parts of a complex-valued signal and outputs its Fourier
transform \, again using separate outlets for the real and imaginary
part. The transform is done on one block of samples (here the block
size is 64 \, Pd's default.) The outputs give the complex amplitudes
of the harmonics of the input signal \, from DC up. The harmonics are
tuned to the fundamental frequency of the analysis \, 1/64th of the
sample rate. If the frequency (in harmonics) is an integer \, the result
is two harmonics symmetric about the Nyquist frequency. Fractional
frequencies spill across harmonics. Changing the initial phase rotates
energy from real to imaginary and back., f 67;
