Thanks to the great work of Chris Cannam and George Fazekas at the C4DM, it is now possible to run vamp plugins directly in python via the vamp module. This is fantastic news, allowing researchers (and everyone else) to integrate algorithms implemented as vamp plugins directly into their python processing pipeline. In this way it becomes much easier to build fully automated experimental (and application) pipelines purely in python, without the need to make external system calls or export the output of a vamp plugin to disk before importing it into python. w00t.
This is great news for Melodia, my melody extraction algorithm that's implemented as a vamp plugin. Now you can use Melodia to extract the pitch contour of a melody from a song directly in python and use the output for further processing, for example you could segment and quantize the contour into notes and export the melody as a MIDI file or a JAMS file.
If you're interested in using Melodia in python, I've created a short tutorial notebook. It should be easy enough to modify it for using other vamp plugins in python too.
