PFFFT

The SoX Resampler Library uses an FFT (Fast Fourier Transform) algorithm called pffft (pretty fast FFT) under the following license:

Copyright (c) 2011 Julien Pommier ( pommier@modartt.com )
Based on original fortran 77 code from FFTPACKv4 from NETLIB (http://www.netlib.org/fftpack ), authored by Dr Paul Swarztrauber of NCAR, in 1985.

As confirmed by the NCAR fftpack software curators, the following FFTPACKv5 license applies to FFTPACKv4 sources. My changes are released under the same terms.
