I also did look at the IPP lib with all the same nice functions from the SPL, but just as the SPL there is something about licenses I believe. The OS FFTW3 package is a nice FFT but without all the other easy to use functions, as you write. I also did not find a other real replacement for the SPL other then IPP.
