The Sound Events Database is a unique collection of recordings of sounds that were made for research purposes. A variety of objects underwent various impacts, scrapes, rolls, and deformations; liquids were dripped, poured, sloshed and splashed. Every type of sound event includes five exemplars, and each exemplar lasts for several seconds (when possible).
