One of the examples on the Annotator extracts most of the Mpeg7 low level 
descriptors. Most of the Mpeg7 descriptors has been review against the 
standard and some of them are not what the are intendeded (notably Spectral 
Kurtosis and Skew). You'll find an accurate documentation on Anyway when they 
fail to implement the standard it is clearly noticed on the doxygen 
documetation. We didn't remove them because even thought they are not the 
standard, they has been proven useful in some contexts.

About fingerprinting, i would suggest to use musicbrainz library. If you want 
to implement such a system in CLAM you are wellcome. Anyway if you explain 
better your goals maybe i could answer you more accuratelly. 

You can browse what do we have by checking some of those classes:
