SAWA (Sonic Annotator Web Application): "SAWA demonstrates audio feature extraction technology developed at the Center for Digital Music, our standard plugin API for audio analysis and a Semantic Web ontology based representation for returning the results of the analysis. It is primarily aimed at researchers who wish to become familiar with these technologies. SAWA may be used as a batch feature extractor, for example, for automatically generating a small reference data set in RDF format. The resulting files can be loaded in a suitable RDF database and queried over, they may be browsed using a Semantic Web browser (e.g. the OpenLink RDF browser) or loaded and visualised with Sonic Visualiser a tool for studying the content of audio files. [For the more Semantic Web savvy: a suitable machine interface (SPARQL endpoint) for retrieving past result automatically is currently under testing but it is not yet available in this public release...]
