My mistake... thanks for clearing that up.
Peace,

If your data is 5120 samples... either truncate it to 4096 samples or pad
it with zeros util you have 8192 samples.
FFTW3 can handle almost any size you want. If the size has
a large prime factor the transform may be significantly
slower, but for something like 5120 = 5 * 2^10 the speed
loss will be quite moderate.
