An FFT can be done in real-time if you assume that real-time can include
a delay between
input and output for startup. Then you get the first set of samples, do
the FFT and get the
next set of samples in paralle. The FFT must be done in less than or
equal to the time to
get the first set of samples. You then have a pipeline doing FFT and
getting the next set
of samples with a delay of one window (frame) time.
Anyone see any problems with that ?
