Overview

This baseline system performs detection of overlapping acoustic events in an office environment, as part of the IEEE DCASE 2016 Challenge - Task 2 (Synthetic Audio Sound Event Detection).
The baseline system is based on supervised non-negative matrix factorization (NMF) with beta-divergence - and uses a dictionary of pre-extracted spectral templates, learned during the training phase.
