Domestic Environment Sound Event Detection (DESED).

This dataset is the synthetic part of the DESED dataset. It allows creating mixtures of isolated sounds and backgrounds.

There is the material to:

  • Reproduce the DCASE 2019 task 4 synthetic dataset
  • Reproduce the DCASE 2020 task 4 synthetic train dataset
  • Creating new mixtures from isolated foreground sounds and background sounds.


If you want to generate new audio mixtures yourself from the original files.

  1. DESED_synth_soundbank.tar.gz : Raw data used to generate mixtures.
  2. DESED_synth_dcase2019jams.tar.gz: JAMS files, metadata describing how to recreate the  dcase2019 synthetic dataset
  3. DESED_synth_dcase20_train_jams.tar: JAMS files, metadata describing how to recreate the dcase2020 synthetic train dataset
  4. DESED_synth_source.tar.gz: src files you can find on github: . Source files to generate dcase2019 files from soundbank or generate new ones. (code can be outdated here, recommended to go in the github repo)

If you simply want the evaluation synthetic dataset used in DCASE 2019 task 4.

The mixtures are generated using Scaper ( [1].

* Background files are extracted from SINS [2], MUSAN [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][5] and manually verified to check the quality and segmented to remove silences.
