SFX Kit – An AI-first sound effect kit with CC0 licence

Wyzowl released SFX Kit, a set of 320 original sound effects published under a CC0 licence that requires no credit and permits commercial use, with the dataset also hosted on Hugging Face. Each sound ships with metadata describing what it is, when to use and avoid it, its length, its sync point and its level, so AI tools can select, time and mix effects as readily as people. The kit spans 25 categories, including 36 interface sounds, 28 notifications, 15 keyboard sounds, 15 booms and bass, 14 logo stings and 12 impacts.

Also on Hugging Face: huggingface.co/datasets/wyzowl/sfx-kit https://huggingface.co/datasets/wyzowl/sfx-kit . 320 original sound effects for videos, animations and interfaces, made to be as easy for AI tools to use as for people. Every sound comes with the data needed to choose it, place it in time and mix it: what it is, when to use it and when not to, its length, its sync point and its level.

For code, load sounds.json https://github.com/wyzowl/sfx-kit/blob/main/sounds.json . Then: 1. Find a sound by what happens on screen: its use for , avoid for and tags say where it fits, and its fits seconds what length of moment. 2. Place it so its sync point meets the moment: start it at that moment minus its sync.at . That one rule works for every sound. 3. Levels: the sounds are matched in loudness as they are, and each says how far it comes down under speech under voiceover db . For people.
