The AudioSet ontology is a collection of sound events organized in a hierarchy. The ontology covers a wide range of everyday sounds, from human and animal sounds, to natural and environmental sounds, to musical and miscellaneous sounds.

Each ontology entry contains a description of the sound event, modified from Wikipedia, Wordnet, or written by us. The ontology is meant to be expandable to meet to research needs of the academic community. Visit our GitHub repository to download and contribute to our growing collection of audio event knowledge.

You can learn more about the construction of the ontology in our ICASSP 2017 paper. Explore the sound classes in the ontology below.
