Sound Event Detection in Synthetic Audio: Analysis of the DCASE 2016 Task Results

no code implementations15 Nov 2017 Grégoire Lafay, Emmanouil Benetos, Mathieu Lagrange

As part of the 2016 public evaluation challenge on Detection and Classification of Acoustic Scenes and Events (DCASE 2016), the second task focused on evaluating sound event detection systems using synthetic mixtures of office sounds.

The bag-of-frames approach: a not so sufficient model for urban soundscapes

no code implementations11 Dec 2014 Mathieu Lagrange, Grégoire Lafay, Boris Defreville, Jean-Julien Aucouturier

The "bag-of-frames" approach (BOF), which encodes audio signals as the long-term statistical distribution of short-term spectral features, is commonly regarded as an effective and sufficient way to represent environmental sound recordings (soundscapes) since its introduction in an influential 2007 article.
