Two weeks before launch, a legal reviewer at a publisher asks one question about the heal pickup in your build: which tool generated it, and under which account? The honest answer is a folder of forty files named heal_final_final.wav and a browser tab you can no longer log into. The review stops until someone reconstructs the chain by hand.
That reconstruction is avoidable. Commercial use of AI-generated audio is mostly a documentation problem before it is a legal one. The rights usually exist somewhere in a terms-of-service page, and the work is proving which page applied to which asset on which day.
What follows is the check I run before a generated cue goes into a build that ships. It is a checklist, not legal advice. For a title with a publisher, a console release, or a rights-holder dispute, a lawyer reads the same documents and tells you what they mean in your jurisdiction.
Read the Terms, Not the Landing Page
The marketing page says you own your generations. The agreement is where the conditions live, and it is usually narrower than the headline. Open the terms for the tier you actually paid for, not the free plan, and read with five questions in mind.
- Assignment or licence? Does the agreement assign ownership of outputs to you, or only grant a licence to use them? The difference matters the moment a client asks for the copyright.
- Is commercial use explicit? It may depend on the plan. Several tools allow commercial use on paid tiers only, and some cap revenue, seats, or the number of shipped products.
- What is restricted? A common clause forbids reselling the raw generation as a standalone asset. That matters for a sound pack and usually not for a cue embedded in a game.
- Can the terms change? If the vendor may revise the licence, the version in force on the generation date is the one that governs your file.
- Is there an indemnity? Read for the words defend and hold harmless. That clause says who pays if a rights holder complains, and what conditions apply.
Copy the page to PDF, or at minimum save the URL and the date you read it. The version in force on the generation date is the one that governs your file.
Output Ownership Is a Separate Question From Training Data
A licence can assign you the output and still say nothing useful about how the model was trained. Those are two risks, not one. The assignment tells you what you may do with the file. The training-data question is about whether the model itself was built on material someone else might claim.
Some providers make explicit claims about licensed or owned training data. Others are silent, and silence is not a warranty. An indemnity typically covers third-party claims that the output infringes copyright, subject to conditions, and it is usually offered on higher tiers rather than the entry plan.
Output assignment does not cure training-data exposure, and a training-data claim does not automatically reach your game. How much either matters depends on jurisdiction, the size of the release, and the posture of the rights holder. That is where the general guide to AI audio copyright and licensing is more useful than a checklist, because the doctrine is not the same in the US, the EU and the UK.
Practical version: where an indemnity exists, keep the document showing you were on an eligible plan on the generation date. Where the provider is silent, treat the asset as higher-risk.
What the Storefront Wants You to Disclose
Platform disclosure is a third question, separate from the licence. Steam, itch.io, Google Play and the console portals all ask some version of whether the game contains AI-generated content, and the wording of those forms changes between submissions. The Steamworks flow distinguishes pre-generated from live-generated content. A heal sound rendered months earlier and shipped in the build is pre-generated.
Audio is rarely asked about as its own category, which is why teams get it wrong. The question is asked at the game level, and one correct answer covers every asset. Answer it from the provenance record rather than from memory, and keep the submitted disclosure text so the next store update matches it.
The same files can run into fingerprinting away from the storefront. A trailer uploaded to a video platform passes through Content ID and systems such as Audible Magic, and a generated cue that happens to resemble a library track can pick up a claim even when the game itself is clean. Disclosure does not clear rights. It only states what you did.
One Record per Asset, Written When You Generate
The record takes about two minutes per sound and replaces an afternoon of reconstruction. Keep it beside the asset, in the same repository as the build, and treat it as a deliverable rather than a personal note.
- Tool and model version. Copy the exact string from the UI or the API request, not "the AI tool". A dated endpoint or pinned model id is better than a product name.
- Account tier and plan name as they stood on the generation date.
- Generation date in ISO 8601, plus the licence URL and the date you read it.
- Prompt and parameters. The full prompt verbatim, any negative prompt, and the exposed settings: seed, duration, temperature, sample rate.
- The raw render and its SHA-256 hash. Keep the generator output untouched, not only the edited master. A 48 kHz, 24-bit WAV is a sensible master; a 16-bit export loses the headroom the next edit may need.
- The edit chain. EQ moves, envelope changes, pitch shifts, layered elements, and the session file that holds them.
- Where the asset ships: game build, store page, trailer, or soundtrack upload.
The seed and the model version are the two fields people skip, and they are the two that let you reproduce the sound after the provider updates the model. A re-render that does not match is not a crisis if the record names the version that produced the file in the build.
The Smaller Checks
Screen for Similarity Before Release
Run the candidate against your own catalog first, then against a commercial library. Normalize both to the same short-term loudness, around -16 LUFS, and compare a 10-second excerpt. A chromagram and a pitch-class histogram catch melodic overlap; spectral centroid and attack time catch timbre matches. Tools such as Chromaprint and AcoustID tell you whether a file is already registered.
If a candidate sits close to an existing heal cue, do not spend an hour EQing around it. Change the seed, drop the shared interval, re-render. Similarity is cheaper to avoid at generation than to argue about after release, and the comparison between AI effects versus stock libraries is worth reading before you decide the library track is the safe option by default.
Put the Tool Clause in the Contract
For client work, the deliverable schedule should say who owns the masters, that you have the right to license them commercially, and which tools were used. Attach the tool list as an appendix. If the client will disclose AI use on a storefront, agree in writing who writes that disclosure. An indemnity cap belongs in the same paragraph, because the client is exposed if a claim arrives.
Keep a Human-Edited Path
A raw generator output is hard to defend as authored work and hard to mix. Give every shipped cue at least one documented edit pass: a shortened attack, a different release, a layered transient, a filter move. Keep the unedited render as a reference so the chain is provable, and keep the session file.
That practice separates using a generator as a sketch tool from shipping its first output. The workflow in a hybrid AI and manual pipeline is the version I would hand to a junior: generate a candidate, cut it to length, replace the tail, print a fresh master at 48 kHz, and archive both files.
What the Checklist Cannot Do
It does not create rights that the terms withhold, and it does not resolve a training-data claim. It also does not replace counsel when the release is large, the publisher has its own legal team, or a console holder asks for documentation. What it does is make the question answerable in an afternoon instead of a week.
Keep the records for the life of the title plus the limitation period in the relevant jurisdiction. A heal sound that ships in a 2026 build may still sit in a storefront years later, and the terms page you read on the generation date will be gone by then. The file you saved is the evidence.
