FMA: A Dataset For Music Analysis

International Society for Music Information Retrieval Conference (ISMIR), 2017.

We introduce the Free Music Archive (FMA), an open and easily accessible dataset suitable for evaluating several tasks in MIR, a field concerned with browsing, searching, and organizing large music collections. The community's growing interest in feature and end-to-end learning is however restrained by the limited availability of large audio datasets. The FMA aims to overcome this hurdle by providing 917 GiB and 343 days of Creative Commons-licensed audio from 106,574 tracks from 16,341 artists and 14,854 albums, arranged in a hierarchical taxonomy of 161 genres. It provides full-length and high-quality audio, pre-computed features, together with track- and user-level metadata, tags, and free-form text such as biographies. We here describe the dataset and how it was created, propose a train/validation/test split and three subsets, discuss some suitable MIR tasks, and evaluate some baselines for genre recognition. Code, data, and usage examples are available at https://github.com/mdeff/fma.

Data

All metadata and features for all tracks are distributed in fma_metadata.zip (342 MiB). The below tables can be used with pandas or any other data analysis tool. See the paper or the usage.ipynb notebook for a description.

Then, you got various sizes of MP3-encoded audio data:

  1. fma_small.zip: 8,000 tracks of 30s, 8 balanced genres (GTZAN-like) (7.2 GiB)
  2. fma_medium.zip: 25,000 tracks of 30s, 16 unbalanced genres (22 GiB)
  3. fma_large.zip: 106,574 tracks of 30s, 161 unbalanced genres (93 GiB)
  4. fma_full.zip: 106,574 untrimmed tracks, 161 unbalanced genres (879 GiB)

See the wiki (or #41) for known issues (errata).

Code

The following notebooks, scripts, and modules have been developed for the dataset.

  1. usage.ipynb: shows how to load the datasets and develop, train, and test your own models with it.
  2. analysis.ipynb: exploration of the metadata, data, and features. Creates the figures used in the paper.
  3. baselines.ipynb: baseline models for genre recognition, both from audio and features.
  4. features.py: features extraction from the audio (used to create features.csv).
  5. webapi.ipynb: query the web API of the FMA. Can be used to update the dataset.
  6. creation.ipynb: creation of the dataset (used to create tracks.csv and genres.csv).
  7. creation.py: creation of the dataset (long-running data collection and processing).
  8. utils.py: helper functions and classes.

Usage

Binder   Click the binder badge to play with the code and data from your browser without installing anything.

  1. Clone the repository.

    git clone https://github.com/mdeff/fma.git
cd fma
  2. <details><summary>Create a Python 3.6 environment.</summary> 
    # with https://conda.io
conda create -n fma python=3.6
conda activate fma

# with https://github.com/pyenv/pyenv
pyenv install 3.6.0
pyenv virtualenv 3.6.0 fma
pyenv activate fma

# with https://pipenv.pypa.io
pipenv --python 3.6
pipenv shell

# with https://docs.python.org/3/tutorial/venv.html
python3.6 -m venv ./env
source ./env/bin/activate
    </details>

  3. Install dependencies.

    pip install --upgrade pip setuptools wheel
pip install numpy==1.12.1  # workaround resampy's bogus setup.py
pip install -r requirements.txt

    Note: you may need to install ffmpeg or graphviz depending on your usage.
    Note: install CUDA to train neural networks on GPUs (see Tensorflow's instructions).

  4. Download some data, verify its integrity, and uncompress the archives.

    cd data

curl -O https://os.unil.cloud.switch.ch/fma/fma_metadata.zip
curl -O https://os.unil.cloud.switch.ch/fma/fma_small.zip
curl -O https://os.unil.cloud.switch.ch/fma/fma_medium.zip
curl -O https://os.unil.cloud.switch.ch/fma/fma_large.zip
curl -O https://os.unil.cloud.switch.ch/fma/fma_full.zip

echo "f0df49ffe5f2a6008d7dc83c6915b31835dfe733  fma_metadata.zip" | sha1sum -c -

echo "0f0ace23fbe9ba30ecb7e95f763e435ea802b8ab  fma_full.zip"     | sha1sum -c -

unzip fma_metadata.zip
unzip fma_small.zip
unzip fma_medium.zip
unzip fma_large.zip
unzip fma_full.zip

cd ..

    Note: try 7zip if decompression errors. It might be an unsupported compression issue.

  5. Fill a .env configuration file (at repository's root) with the following content.

    AUDIO_DIR=./data/fma_small/  # the path to a decompressed fma_*.zip
FMA_KEY=MYKEY  # only if you want to query the freemusicarchive.org API

  6. Open Jupyter or run a notebook.

    jupyter notebook
make usage.ipynb
