extracting MPEG-7 low-level audio descriptors using essentia According to https://www.ntnu.edu/documents/1001201110/1266017954/DAFx-15_submission_43_v2.pdf, the audio processing toolbox Essentia includes the 100% of MPEG-7 low-level audio descriptors. However I have been trying to use it to extract them from a .wav file, and I can't find their names in Essentia's documentation.

My question is: Does Essentia actually include those descriptors out of the box (I mean, as a function, as it does with the MFCCs for instance), but maybe with different names than the originals? Or is it that it only includes "general tools" (as Spectrum extractors) to help with the actual extraction of those features?

In either case, could someone please explain here (or refer to a place where it is explained) how to get the seventeen MPEG-7 low-level descriptors USING ESSENTIA?
Looking at the Essentia documentation, the MPEG-7 isn't listed directly as a function from where you can extract features. 

The audio descriptors in the MPEG-7 standard are listed here. I think you will have to take use various functions to create your own feature vector. Hope this helps!
