Installation

Recommended install

Take into account your changes of the code in the desed/ folder.

• git clone https://github.com/turpaultn/DESED
• cd DESED
• pip install -e .

In this case, all your changes in desed folder will be taken into account

Use desed in other projects

Copying code from synthetic/code/ or real/code/ folders without changing desed/ content

• pip install desed

Usage

Download

import desed
desed.download_real("./data/dataset")
desed.download_desed_soundbank("./data/soundbank")
# Additional sets:
desed.download_fuss("./data/FUSS")
desed.download_fsd50k("./data/fsd50k", gtruth_only=True) # groundtruth only to use annotations for FUSS

Generate soundscapes

• See examples

Short description of DESED dataset

There are 3 different datasets:

• Recorded soundscapes (a.k.a. real).
• Soundbank to generate synthetic soundscapes.
• Public evaluation (recorded soundscapes) (a.k.a., Youtube in DCASE19, Vimeo is not available): DESED public eval

DESED dataset is for now composed of 10 event classes in domestic environment.

You can

• Use only the real dataset.
• Use the soundbank to create your own synthetic soundscapes. (generate new mixtures using Scaper [1])
• Reproduce the soundscapes made for DCASE task 4.

Long Description

There are 3 different datasets:

• Recorded soundscapes (a.k.a., real).
• Synthetic soundbank + DCASE task 4 soundscapes: DESED_synthetic
• Public evaluation (recorded soundscapes) (a.k.a., Youtube in DCASE19, Vimeo is not available): DESED public eval

All these datasets contain an "audio" folder associated with a "metadata" folder so they can all be grouped together by merging them

DESED dataset is for now composed of 10 event classes in domestic environment. The soundbank can include annotated data outside of the 10 classes to allow the creation of more realistic soundscapes.

Overview:

• Recorded soundscapes:

  • Verified and unverfied subset of Audioset.
    • Unlabel_in_domain data: Unverified data have their label discarded: 14412 files.
    • Weakly labeled data: training data have their labels verified at the clip level: 1578 files.
    • Validation data have their labels with time boundaries (strong labels): 1168 files.
    • Evaluation public files: Youtube files 692 files

• Soundbank:

  • Background files are extracted from SINS [2], TUT[7], 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.
  • Mixtures are described in Generating new synthetic soundscapes below.
  • Soundbank:
    • Training: 2060 background files (SINS) and 1009 foreground files (Freesound).
    • Eval: 12 (Freesound) + 5 (Youtube) background files and 314 foreground files (Freesound).

• DCASE 2019

  • It uses synthetic soundbank, recorded soundscapes, and public evaluation data (a.k.a., Youtube eval during DCASE19).
  • If you want more information about DCASE19 dataset visit DCASE 2019 task 4 web page
  • If you only want to download DCASE19 files, go to dcase2019 task 4.

FAQ

• I have a problem downloading the recorded soundscapes. How do I do ?

If you're in a country with youtube restrictions, you can try to use a VPN and the --proxy option from youtube-dl. You can also try to upgrade youtube-dl since it is regularly updated. Finally, if you succeeded to download most of the files, you can send your missing files (missing_files_XXX.tsv) by mail to Francesca Ronchini, Romain Serizel and/or Nicolas Turpault.

• I have a problem with SINS download. How do I do ?

• Why don't we have a single dataset repository ?

The synthetic sounbank or recorded soundscapes can be used independently for different purposes. For example, one can create new synthetic soundscapes and evaluate his system on synthetic data only to focus on a specific problem.

• Why audio is not always included in the repository ?

Because of licenses issues. (Example of SINS in the training soundbank) We do not have the problem for evaluation data because we try to overcome the problem after running into this issue.

• How do I evaluate and compare my system with other methods using this dataset ?

In this paper you can refer to the column 'Youtube' and for further study, you can cite the DESED public evaluation set.

Important updates

• 26th February 2020, v1.2.5, refactor, get rid of bash files and ease the download through the package.
• 7th December 2020, v1.2.2, ease the download of soundbank (with or without pre-split validation)
• 23th April 2020, v1.2.0, update the generation procedure (add_fg_event_non_noff) to use all parts of files longer than the duration of the soundscapes created + Add possibility to use only background from certain labels (i.e: sins or tut).
• 18th March 2020, v.1.1.7, update DESED_synth_dcase20_train_jams.tar of DESED_synth. They use pitch shifting, while the others didn't. These are the final JAMS used for dcase2020 baseline. Also commenting reverb since not used for the baseline.
