## Description
This repository gives the information and the code to download the data, reproduce the synthetic dataset used in DCASE 2019 task 4 and examples of how you can create your own data (using [Scaper](https://github.com/justinsalamon/scaper) [[1]](#1)).

You can find information about this dataset in this paper: [link](https://hal.inria.fr/hal-02160855).
The evaluation part was submitted to ICASSP and will be updated later.

* Background files are extracted from SINS [[2]](#2), MUSAN [[3]](#3) or Youtube and have been selected because they contain a very low amount of our sound event classes.
* Foreground files are extracted from Freesound [[4]](#4)[[5]](#5) and manually verified to check the quality and segmented to remove silences.
