Cannam, C. Sandler, M. 2009 C4DM White Paper 04/2009 We describe the construction of SAWA a simple Web-based system for automated audio analysis. This system is capable of calculating an easily extended set of musically meaningful features such as beat, tempo, and key estimates from uploaded audio files, returning the results as rich RDF data suitable for interlinking on the Semantic Web. Unlike existing systems, our application is built on open and reusable components and provides an example of quick and straightforward development. 10 Matthias Mauch Chris Cannam Matthew Davies Christopher Harte Sefki Kolozali Dan Tidhar M.
