(they also support running on the GPU but that is probably outside the
scope of numpy or scipy).  It used to be proprietary but now it is under a
BSD-3-Clause license.  It seems it supports non-power-of-2 FFT operations
as well (although those are slower).  I don't know much beyond that, but it
is probably worth looking in
