Freesound Loop Dataset

This dataset contains 9,455 loops from Freesound.org and the corresponding annotations. These loops have tempo, key, genre and instrumentation annotation.

Dataset Construction

To collect this dataset, the following steps were performed:

  • Freesound was queried with "loop" and "bpm", so as to collect loops which have a beats-per-minute(BPM) annotations.

  • The sounds were analysed with AudioCommons extractor, so as to obtain key information.

  • The textual metadata of each sound was analysed, to obtain the BPM proposed by the user, and to obtain genre information.

  • Annotators used a web interface to annotate around 3,000 loops.

Dataset Organisation

The dataset contains two folders and two files in the root directory:

  • 'FSL10K' encloses the audio files and their metadata and analysis. The audios are in the 'audio' folder and are named '<freesound_sound_id>.wav'. The AudioCommons analysis of the loops is present in the 'ac_analysis' directory, while the Essentia analysis of the loops obtained through the Freesound API is on the 'fs_analysis' directory. The textual metadata for each audio can be found in the 'metadata.json'. Finally, the audio analysis provided by the algorithms which were benchmarked in the paper is on the 'benchmark' directory.

  • 'annotations' holds the expert provided annotation for the sounds in the dataset. The annotations are separated in a folder for each annotator and each annotation is stored as a .json file, named 'sound-<freesound_sound_id>.json', with a key for each of the features extracted.

Licenses

All the sounds have some kind of Creative Commons license. The license of each sound in the dataset can be obtained from the 'FSL10K/metadata.json' file
