This is a SC plug-in for multiple fundamental frequency tracking, after Anssi Klapuri's 2008 paper 'Multipitch analysis of polyphonic music and speech signals using an auditory model'

PolyPitch is released under GNU GPL 3, for SuperCollider 3, by Nick Collins

Note: I provided this SuperCollider plugin here from Nick Collin's website in order to provide a convenient way to download a copy of PolyPitch with help files that have been updated to the .schelp format (for newer versions of SuperCollider) as well as up to date precompiled binaries for the newest SuperCollider version (files ending with .scx or .so etc).

To install: put the PolyPitch folder in your SC extensions directory. Copy into that folder a PolyPitch.scx file. There are some prebuilt ones provided, and compilation instructions also follow.

Prebuilt binaries can be found on the "releases" tab above.

To compile for platforms other than Mac, using the SC native FFT interface, comment out: \#define OSXACCELERATENOTSCFFT in MultipitchHeader.h

Compilation requires libsamplerate from http://www.mega-nerd.com/SRC/

Make sure in CMakeLists.txt that the 64bit library linking line is uncommented and 32bit is commented Then on the command line (assuming CMake is installed and you have the source code of SuperCollider at /data/gitprojects/scdev/supercollider):

cmake -DSC_PATH=/data/gitprojects/scdev/supercollider -DCMAKE_OSX_ARCHITECTURES='x86_64'
make
