Updated October 2026 · Sound design and sound effects
A sound effects licence sets out what you may do with a recorded sound, such as using it in a video, a game or an advert, and whether you can share or resell it. Licences differ widely, and some restrict commercial use, platform use or redistribution. Read the terms, keep a record of the licence, and check every sound before publishing.
Sound effects are often bought, downloaded or found online, and many creators assume that anything they can access is free to use. That assumption can lead to takedowns, claims or a lost project. A sound effects licence is a set of terms, and each one decides what the creator may do with the sound. Understanding the common types of licence, and checking each one before use, is part of the professional habit of sound design.
This post explains the common licence types, what they usually allow and restrict, and the checks to make before a sound goes into a video. It is general guidance, not legal advice, and the terms of each licence matter more than any summary.
A recorded sound is protected by copyright, and the person who recorded it may own the rights, even if the sound is short. Using it without permission can lead to a takedown, a claim or a demand for payment. A licence is the permission, and it defines the limits of that permission. Using a sound outside its licence is the same as using it without one.
Licences commonly restrict redistribution, which means you may not share or resell the raw sound. They may limit use in products, such as a sound library or a game asset. Some restrict use in adverts, political content or content that could be considered offensive. Some require credit, and some limit the number of projects or the platform. Read each restriction, and check it against your use.
A record is the best protection. Keep a folder of the licences, with each sound’s name, source and terms. When a question arises, the record shows what was agreed. Many creators lose track of licences over time, and a simple log prevents that. The same discipline applies to music, as covered in the intro music post.
A sound offered for free may still have terms. It may require credit, forbid commercial use or restrict redistribution. Check the terms of every free sound, and treat “free” as the start of a check rather than the end of one.
Recording your own sound effects removes the licence question entirely, because you own the recording. It is also a creative advantage, since your sounds are unlike anyone else’s. The next post in this series covers that approach, as set out in the home recording post.
Some free licences ask for a credit, and the credit may need to appear in the description, the end credits or the sleeve notes, depending on the project. Read the wording of the licence and the platform's own rules, since they may require the credit in a particular place. Add the credit to the project file as soon as you add the sound, so it is not forgotten at delivery.
A sound downloaded years ago may have come with a different licence from the one that applies now. Keep the page, the date and the licence text you saw when you downloaded it, and check the source again before a major release. The record protects you if the rules are questioned later.
When a licence depends on a purchase or a sign-up, keep the receipt, the account page or the email that confirms it. Store that proof with the project, not in a folder that gets cleared at the end of a job. If a client asks later whether a sound was cleared for their use, a quick answer is worth far more than a long search.
Licence terms vary widely, and this post cannot cover every licence. Where a project has significant value or risk, take advice from a professional who understands the local rules. Treat the terms as binding, and read them before you rely on a sound.
Before publishing, check the licence of each sound in the final mix. The Vocal Checker shows clipping, noise and level problems in a recording you own, and the Tunedzy Go page covers cleaning phone recordings. For the wider sound design context, read the sound design basics post in this series.
Spot clipping, noise, rumble and level problems. Runs in your browser, nothing is uploaded.
Only if its licence allows your use. Check the terms, including any credit requirement.
Yes. Length does not remove the rights, so check every sound, however short.
Limits on commercial use, redistribution or the type of product the sound is used in.
