ANNOUNCEMENT 
I am pleased to announce the initial release of "upfirdn."   This package
provides an efficient polyphase FIR resampler object (SWIG-ed C++) and some
python wrappers.   

  https://opensource.motorola.com/sf/projects/upfirdn

MOTIVATION 
As a long time user of MATLAB and the Signal Processing Toolbox, I have
missed an "upfirdn" analogue in numpy / scipy since I switched over to
python a couple years ago.  I've been looking for a way to contribute to the
wider numpy / scipy community since I love these tools and appreciate all
the efforts of those who have developed them.  Since we have the polyphase
resampling functionality within Motorola and I use it for my work, I thought
it best to go the "official route" and get approval from my company to
publish it under a BSD compatible license. 

NOTES TO USERS AND REGARDING INSTALL 
It is my hope that others find this functionality useful.  Suggestions for
improvements or bug reports are welcome.  As installation is an area that I
am very green, I recommend only installing it locally for now, e.g. 
      python setup.py build_ext -i 
or even just 
      make 
I'd like to spend some time learning more about distutils and release a
version with a more user-friendly install.
