Sonic Annotator is a utility program for batch feature extraction from audio 
files.  It runs Vamp audio analysis plugins on audio files and can write the 
result features in a selection of formats, in particular as RDF using the 
Audio Features and Event ontologies.
A somewhat experimental first public release (0.1) is now available.
