BECCA, a general machine learning algorithm, processed the audio from an excerpt of J.R.R. Tolkein's The Hobbit. It created a hierarchy of tonal-temporal features unsupervised, as well as a model of their occurrence. Based on this, BECCA determined the novelty of the input and identifies unusual audio events.
