DCASE2017 Task 3: Real-life sound event detection winning method

Python implementation

Sound event detection (SED) is the task of recognizing the sound events and their respective temporal start and end time in a recording. Sound events in real life do not always occur in isolation but tend to considerably overlap with each other. Recognizing such overlapping sound events is referred as polyphonic SED. Performing polyphonic SED using mono-channel audio is a challenging task. These overlapping sound events can potentially be recognized better with multichannel audio. The proposed MSEDnet intends to do polyphonic SED using multichannel audio. MSEDnet was first proposed in 'Sound event detection using spatial features and convolutional recurrent neural network'. It recently won the DCASE 2017 real-life sound event detection. We are releasing a simple vanilla code without many frills here.

Reference systems

DCASE2018 Baseline system for acoustic scene classification

This is the baseline system for the Detection and Classification of Acoustic Scenes and Events 2018 (DCASE2018) challenge's acoustic scene classification task.


DCASE2017 Baseline system

Python implementation
This is the baseline system for the Detection and Classification of Acoustic Scenes and Events 2017 (DCASE2017) challenge tasks. The baseline system is intended to lower the hurdle to participate the DCASE challenges. It provides an entry-level approach which is simple but relatively close to the state of the art systems to give reasonable performance for all the tasks. High-end performance is left for the challenge participants to find. In the baseline, one single low-level approach is shared across the tasks by application-specific extensions. The main idea of this is to show the parallelism in the tasks settings, and show how easily one can jump between tasks during the system development.

DCASE2016 Baseline system

This is the baseline system for the Detection and Classification of Acoustic Scenes and Events 2016 (DCASE2017) challenge tasks. It is proveded in two parallel implementations (Python and Matlab) to lower the hurdle from switching from Matlab to Python.

sed_vis — visualizing sound event detection output

sed_vis is an open source Python toolbox for visualizing the annotations and system outputs of sound event detection systems. It provides an event roll-type of visualizer to show annotation and/or system output along with the audio signal. The audio signal can be played and indicator bar can be used to follow the sound events.
