Where to Legally Download Sound Effects and How to Read Licences

Every creator eventually needs the sound of rain, footsteps on gravel or a creaking door. Good news: there are plenty of legal sources. Bad news: each has a different licence, and misreading one sentence can cost you a taken-down video or a legal dispute.

Where to look

Freesound.org — the largest community library. Quality varies, but there are treasures. Careful: every sound can carry a different licence (CC0, CC-BY, non-commercial variants) — check each file individually.

A Sound Effect — a curated marketplace of professional libraries. You pay, but you know exactly what you're buying and the licence is uniform (royalty-free for use in projects).

Commercial libraries (BOOM Library, Sonniss, Pro Sound Effects) — the professional standard. Sonniss also gives away gigabytes of sounds every year in its GDC bundle — legally and royalty-free.

Licences in a nutshell

• CC0 — public domain. Use anywhere, commercially too, no attribution.
• CC-BY — commercial use allowed, but you must credit the author (in credits or the description).
• CC-BY-NC — non-commercial projects only. A monetised YouTube video already counts as commercial use!
• Royalty-free — pay once, use repeatedly with no further fees. You're not buying the sound, you're buying a licence — read whether it covers e.g. games or broadcast.
• Rights-managed — a licence for one specific use (project, territory, period). The most expensive; rare in everyday work.

Three rules of practice

1. Keep proof of the licence for every downloaded sound (screenshot, invoice, URL). You won't remember in two years.
2. Write attributions as you go, not at export — keep a text file in the project.
3. The most valuable library is your own. What you record, you own outright — and nobody else has it.

I teach how to record your own effects and build a library from them in the SFX & Atmospheres course.
