Mixing and Mastering AILast updated 21 September 2026.
These terms govern your use of mixingandmastering.ai. By creating an account, buying a token or running a job, you agree to them. If anything here is unclear, contact us before you buy.
1. Who we are
mixingandmastering.ai is operated by Audio Mixing Mastering B.V. ("we", "us"), a company registered in the Netherlands. You can reach us at help@mixingandmastering.ai.
2. Your account
You need an account to run a job. You can create one with an email address and password or with Google. Keep your login details to yourself: you are responsible for what happens under your account. Give us accurate information and keep it current, and tell us straight away if you think someone else has access.
You must be old enough to enter into a contract where you live. If you use the service for a company, you confirm you are allowed to accept these terms for it.
3. What the service does
The engine mixes and masters audio you upload, and runs the individual tools listed on the tools page. It is a self-serve product: you choose the settings, the engine renders, and the result appears in your account. Every decision the engine makes is written down for you.
We describe what each service does as accurately as we can, but audio work is a matter of judgement and taste. The quality of the result depends on the quality of what you upload. We do not promise a specific artistic outcome, a placement, or that a result will be accepted by any distributor or platform.
4. The music you upload
Your music stays yours. Uploading it does not give us any ownership of it.
You confirm that you own the material you upload or otherwise have the right to use it, and that processing it does not infringe anyone else's rights. You are responsible for the files you send us.
We use your files only to run the job you asked for. We do not use customer projects to train the engine. Training reads only our own licensed catalogue.
5. Plans and billing
Plans are metered in minutes of audio. A four minute song costs four minutes.
- Free. 10 minutes, once, so you can hear the full result before paying. Exports on the free plan carry a watermark.
- Starter. $9.99 a month, 60 minutes a month.
- Studio. $19.99 a month, 200 minutes a month.
- Enterprise. $99.99 a month, unlimited minutes.
Prices are in US dollars and exclude any tax that applies where you live. Payments are handled by Stripe. We never see or store your full card details.
Subscriptions renew automatically at the end of each billing period until you cancel. Monthly minutes reset each period and do not roll over.
6. Cancelling a subscription
You can cancel at any time, from your account, with no notice period and no cancellation fee. Cancelling stops the next charge. Your plan stays active until the end of the period you have already paid for, and after that your account moves to the free plan. We do not refund the remainder of a period you have already paid for.
7. Tokens
You can also pay per job with tokens, with no subscription. A token costs $1.99, and tokens never expire. One token runs one service:
- Most single tools: 1 token, $1.99.
- Stem separation, audio restoration and Suno shimmer removal: 2 tokens, $3.98.
- AI Mastering: $4.99.
- AI Mixing: $6.99.
- A full AI mix and master: $9.99.
The simple utilities, including the BPM finder, audio trimmer, LUFS analyzer and sample rate converter, are free to use.
The price you see at checkout is the price you pay. If a price on any other page disagrees with the checkout, the checkout is correct, and we would be grateful if you told us.
8. Refunds
Because a job starts the moment you submit it and is delivered as soon as it finishes, you are asking us to begin immediately. By submitting a job you accept that performance starts right away and that any statutory right of withdrawal ends once the run has started.
- Services are non-refundable once a job has run. A completed render is delivered work.
- Tokens are non-refundable. They do not expire, so an unused token stays available in your account for whenever you need it.
- Subscription periods are non-refundable. You can cancel at any time to stop future charges.
This does not affect your rights where the law says otherwise. If the engine failed to deliver, charged you twice, or charged you for something you did not buy, write to help@mixingandmastering.ai and we will put it right.
9. Acceptable use
Do not upload material you have no right to use. Do not use the service to build a competing engine, to resell access, or to scrape, reverse engineer or overload it. Do not attempt to get around plan limits, watermarks or payment.
We can suspend or close an account that breaks these rules or that is used fraudulently. Where it is reasonable to do so, we will tell you why first.
10. Availability
We work to keep the service running and fast, but we do not promise it will be uninterrupted or error free. We may change, pause or retire features. If we retire something you rely on, we will give you reasonable notice where we can.
11. Liability
Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud.
Subject to that, we are not liable for lost profits, lost revenue, lost opportunities or lost or corrupted data, and our total liability to you for any claim is limited to what you paid us in the twelve months before the claim arose.
Keep your own copies of your source files. We are not a backup service.
12. Changes to these terms
We may update these terms. If a change matters to you, for example a change to pricing or to refunds, we will tell you before it takes effect. Continuing to use the service after a change means you accept the updated terms.
13. Law and disputes
These terms are governed by Dutch law, and disputes go to the competent court in the Netherlands. If you are a consumer, this does not take away the protection of the mandatory law of the country you live in, and you may also use the European Commission's online dispute resolution platform.
