plamere, thank so much for responding so quickly. I tried to build the latest Echoprint-codegen Windows executable using Visual Studio 2013 (after I successfully installed Boost/zlib C++ libraries using VS2013 online installer). Unfortunately, I'm getting errors when building it. I already opened a new issue on Github for someone to update the package for it to work with the current version of VS2013.
I would be VERY grateful if you could PLEASE point me to the latest compiled working Echoprint-codegen Windows exe (and all latest binary dependencies, ffmpeg, etc). I can't find a single copy anywhere. The only thing I could find was the ENMFP_codegen executable: http://static.echonest.com/ENMFP_codegen.zip which is NOT what I'm looking for.
Thanks again for the quick reply.
