Sample licences: royalty-free, public domain and Creative Commons.

The phrase most often misread in this sector is “royalty-free”. It is worth starting with the literal question: What does royalty-free mean? Two words that seem to promise one thing—that something costs no money—but actually state another: once the material has been paid for, no royalty is paid for each use. These are different concepts, and confusing them causes most of the problems.

This subject has a legal aspect, which should be stated at the outset: what follows is educational material for understanding the terms, rather than legal advice. Rules vary between countries, and every case has its particular circumstances; if you have a doubt about a work you intend to publish, consult a professional.

What each licence really means

Before the nuances, establish the framework. Broadly speaking, there are three routes for using someone else’s material: the work is in the public domain, the rights holder gives you permission or a licence, or an applicable legal limitation or exception exists. The U.S. Copyright Office presents it this way in its material for musicians, and it is a structure that can help you think in any jurisdiction.

A second fact explains almost all the misunderstandings: a musical composition and its recording are two separate works. The composition—lyrics and music—and the master—the specific recording—are created and licensed separately. That means a work can be in the public domain while its recording remains protected, and vice versa.

With that framework in place, the table above summarises the four situations you will encounter. Pay attention to the “What it does not permit” column: none of them makes you the exclusive owner of the sound.

Buying samples today: individual packs and subscriptions

Buying samples no longer means going to a shop and taking home a CD of sounds. There are now two models, and it helps to know what you acquire in each:

• Individual packs. You pay once and receive a specific package. Payment covers a licence to use it; proof of purchase is your evidence.
• Subscription. You pay a fee and download using credits. The licence is granted per download, and the important point is whether it survives when you stop paying.

In both cases, what you buy is a royalty-free licence to use the material: you pay for the material once, rather than for each playback. Splice and similar services write their own conditions, so the relevant detail is always in the specific service’s terms, rather than the label.

Splice answers that question in its official FAQ: downloaded sounds are covered by a perpetual licence, so you can continue using them even if you cancel or pause your subscription. It also clarifies what almost nobody reads: the licence is non-exclusive, meaning other people can use the same sounds without infringing your work.

That last point is what makes “royalty-free” a matter of permissions rather than ownership. You own your new recording, but not the sounds you downloaded: you cannot resell or repackage them.

Another practice deserves attention: services offer to generate a licence certificate in PDF listing the samples you downloaded, intended to be shown to a distributor. It is not a bureaucratic formality: most distribution platforms ask you to declare third-party material, and that document is the answer. If you plan to publish using subscription material, generate the certificate and keep it with the project.

For context: if you want places to buy material with reliable conditions, see the guide to legitimate sources for buying music; if you are a DJ seeking catalogues with specific conditions, see DJ pools and promotional platforms.

Free libraries: the quality and licensing trap

Free libraries exist, are useful, and often have a perfectly usable licence. The problem has two sides.

First, quality: free material mixes origins, and you do not always know whether a file is the author’s own recording, a compilation or something recycled from elsewhere. A loop with its background cut off or a master compressed twice can become problems much later.

Second, licensing: free material is where “it’s free; do whatever you like” is most often repeated. Free can mean at least three different things: a public-domain work, a Creative Commons work or no-cost material with a limited-use licence. They are not the same, and only the first and second depend on copyright; the third is a contract between you and whoever offers it.

The habit that avoids problems is simple: keep the page or text of the licence alongside the file it came from. Two lines in a text file resolve doubts you cannot substantiate years later. The guide to free and promotional music develops this approach for material circulated through download gates.

Public domain: when a work enters it and what it is not

Public domain does not mean “it is on the internet”; it means the work is no longer protected by copyright, or never was. In that case, you can copy, adapt and publish it without asking permission.

The nuances that matter:

• Not every part enters at the same time. Since the composition and recording are two works with different rules, an old musical piece may be free while a performance recorded forty years ago is not.
• Duration is not universal. It depends on the country and type of work. What is free in one market may remain protected in another, which affects international releases.
• Being “very old” is not enough on its own. Copyrighted recordings can be based on very old works, and some works also lost protection through failure to meet formal requirements.

A practical application in production: if you work with classical, home-recorded or archive material, checking which version you use is just as important as checking the arrangement. If you make a derivative work from public-domain material, the new work is yours, but the decision remains yours too.

Creative Commons: the four clauses that matter

Creative Commons does not remove rights: it redistributes them. The author retains copyright and publishes the work under conditions anyone can accept. The four clauses, translated directly into your situation:

• BY (Attribution). You can use, adapt and monetise if you credit the author. It is the most permissive and most common.
• NC (NonCommercial). You cannot use it for anything intended to make a profit. For a DJ publishing monetised sets or selling edits, that effectively excludes the work.
• SA (ShareAlike). If you adapt the work, you publish the derivative under the same licence. It links projects rather than freeing them.
• ND (NoDerivatives). You cannot modify the work. A trimmed, reversed or recontextualised sample is an adaptation, so ND and sampling do not fit together.

One detail is frequently misread: Creative Commons licences are irrevocable while their conditions are met, but they do not add permissions for third-party rights the work may contain—performances, photographs or trademarks. Authorship does not guarantee that the person publishing it could license everything.

For publishing, this means a track containing CC BY material needs visible credit in the description; with BY-NC, that use no longer fits; with BY-ND, trimming the sample is already incompatible.

What to check before publishing

The final checklist, in the order you should follow it:

1. Where did the file come from? A purchased pack, subscription, free library, your own recording or a record. Note the source.
2. Which licence covers that origin? A purchased royalty-free licence, the service’s terms, CC with its clauses or public domain.
3. Which rights does the work have? Remember that composition and recording are two separate things: the answer may differ for each.
4. Do I have the evidence? An invoice, licence certificate or screenshot of the page, kept with the project.
5. Are there credit obligations? Attribution, declarations to distributors or registration with your collecting society.

If you cannot answer any point, do not assume: change the material or resolve the doubt before publishing. The next guide covers the case where the source is not a pack, but an already released record.

Next step

When the material comes from a record rather than a shop, the problem changes scale: clearance and cutting technique enter the picture. Continue with Sampling records: clearance, chop, warp, time stretch and slicing.
