Frequently asked questions
- Are these sound effects really free for commercial use?
- Yes. Every sound on SFXMint is dedicated to the public domain under CC0 1.0. Use them in commercial games, videos, apps and products — no attribution, no signup, no license fees.
- Where do the sounds come from?
- All sounds are generated by open-source AI models (Stable Audio 3) or procedural synthesis. Nothing is scraped or copied from other sound libraries, so the catalog is copyright-clean.
- Can I hotlink the audio files directly?
- Yes. Audio URLs are permanent, immutable and CORS-enabled — you can embed them directly in your app or website. There is also a free, no-key JSON API.
- What formats are available?
- Every sound is available as 128kbps MP3 and 44.1kHz 16-bit WAV, loudness-normalized to -16 LUFS.
- Can I use these in Unity, Godot, Unreal or a video editor?
- Yes. The 44.1kHz 16-bit WAV files import directly into Unity, Godot, Unreal, Premiere, DaVinci Resolve and CapCut; use the MP3s for web projects. CC0 covers commercial games and monetized videos.
