Fingerprinting with Chromaprint algorithm

As we are gradually expanding Essentia with new functionality, we have added a new algorithm for computation of audio fingerprints, the Chromaprinter. Technically, it is a wrapper of Chromaprint library which you will need to install to be able to use Chromaprinter.

The fingerprints computed with Chromaprinter can be used to query the AcoustID database for track metadata. Check a few examples of how Chromaprinter can be used in Python here. To start using this algorithm now, build the latest Essentia code from the master branch.
