Hello all,
So I'm attempting to do some FFT work with an AU I'm developing. In
the process function you get passed 1024 samples at a time. I was
hoping to do an FFT of size 2048 or 4096, although I'm confused about
how to do this. Do I just read in the 1024 samples and zero pad it
until it gets to a larger size (2048 or 4096). But I've heard zero
padding doesn't help increase resolution. I was thinking of just
making a buffer to hold the data until I get enough to do the FFT, but
then I would think that would cause a bit latency, since I would have
to keep waiting for the buffer to be filled.
Any thoughts?
Thanks,
Ryan
