Looking for Freesound Datasets ?

You are actually at the right place! Freesound Datasets is now called:

Freesound Annotator

Explore, download and contribute to our datasets

The FSD is a large-scale, general-purpose dataset composed of Freesound content organised by the AudioSet Ontology

... more to come!

Our vision ...


The datasets creation process should be as transparent
as possible since data science results heavily depend on it


Data should be released under open licenses to
facilitate its distribution and help reproducible research


Datasets should be dynamic in the sense that
they can evolve over time in quality and quantity

... and our plan!

Freesound content

We leverage Freesound (>370k sounds) as a
source of open audio content for creating datasets


We rely on the community to sustainably crowdsource high-quality
sound annotations and to improve our platform workflows

Freesound Annotator

Builds and maintains datasets following the outlined principles of
transparency, openness, dynamic character, and sustainability
