About SFXMint

SFXMint is a copyright-clean sound effects library. Every sound here is created by open-source AI models or procedural synthesis — nothing is scraped, re-hosted or copied from other sound libraries. Because we generate everything ourselves, we can dedicate the entire catalog to the public domain under CC0 1.0.

That means you can use any sound in commercial games, videos, podcasts, apps and products with no attribution, no signup and no license fees. Hotlinking the audio files directly into your own project is allowed and encouraged — URLs are permanent and immutable.

For developers and AI agents, the whole library is also available through a free JSON API that requires no API key. See the API docs for endpoints and examples.

Sounds are AI-generated — Powered by Stability AI — and receive per-format file checks when those checks are available. We verify each file's format, duration and checksum automatically; whether a sound fits a particular scene is a listening judgment, and we label that separately. Synth-style sounds are additionally produced with our in-browser procedural generators.

SFXMint is built and maintained by flreey, an independent developer. The API, the MCP server and the integration guides are developed in the open at github.com/flreey/sfxmint-mcp.

Choosing and reviewing sounds

Catalog titles and prompts describe the intended event. File checks, acoustic measurements and listening judgments answer different questions. Our sound-selection guide compares concrete examples, explains the measurements and gives you a checklist for trying them in a finished scene.
