These Terms of Use ("Terms") govern your use of Music Waveform, the audio visualizer and waveform video maker available at music-waveform.com (the "Service"). By using the Service, you agree to these Terms. If you do not agree, please do not use the Service.
Music Waveform lets you load an audio file and generate an animated waveform that you can preview and export as an MP4 video. All processing happens locally in your browser; the Service does not upload your files. The Service is provided free of charge. As things stand today, eight waveform styles, every export format and every resolution up to 2560 px are free, with no account, no watermark and no limit on how many videos you export. An optional one-time Pro add-on, described in section 5, adds further features for a one-off price. Where the line between free and Pro sits is not fixed; section 5 says what the free tier always keeps.
You must be able to form a binding contract to use the Service. If you use the Service on behalf of an organization, you represent that you are authorized to accept these Terms on its behalf.
You are solely responsible for the audio files you load and for the videos you create with the Service. You represent and warrant that:
Because your files are processed only on your device, you retain all rights to your audio and to the videos you export. We claim no ownership over them.
You agree not to:
Pro is an optional one-time purchase that adds features to the Service. Which feature sits on which side of the line is not fixed: a feature that is free today may later be moved into Pro, and we reserve the right to do so.
What will not change is that the free tier stays usable on its own, for its normal purpose, without paying. Whatever moves, the free tier keeps everything needed to produce a good-quality waveform video — loading your own audio, a waveform you can style, a standard export format, and a resolution and encoding quality high enough for ordinary use — and it keeps unlimited exports, with no account and no watermark. The free tier will not be turned into a trial, a quota, or a watermarked preview of a paid product.
The purchase is made through Stripe, which acts as the merchant of record. Stripe is the seller for that transaction, collects the payment, applies any tax due in your country and issues your receipt. Stripe's own terms govern the sale itself, and any question about a charge, a refund or an invoice is answered fastest there.
That is true nearly everywhere and not quite everywhere: Stripe assumes the indirect tax in roughly eighty countries. Where your purchase falls outside that coverage, it is a plain Stripe payment and the provider named in the legal notice is the seller, with the same obligations towards you. The licence described below is granted by the provider in either case.
You receive an unlock key. It is a licence to use the add-on's features, granted to you personally and not transferable or resellable; the Service's own software remains ours under section 6. The key is checked inside your browser, so unlocking is per browser: clearing your site data, or moving to another device or browser, means entering the key again. Keep your receipt.
Your right of withdrawal. For a distance purchase, EU consumer law gives you fourteen days to change your mind. Digital content is the one case where that right can end early — but only if you expressly asked for immediate delivery and expressly acknowledged losing the right, at the moment of buying. Whether and how that consent is taken is part of the checkout, which the merchant of record operates; what it says there governs, and this page does not presume to have waived anything on your behalf.
And separately, the legal guarantee of conformity. This one does not depend on the fourteen days and cannot be waived at checkout or anywhere else. The add-on has to match what this page describes. If it does not — if a feature listed here is missing, or it fails on a browser it is meant to support — you are entitled to have that put right, and if it cannot be, to a price reduction or to cancel and be refunded. You have two years from the date of supply for a one-off purchase of digital content like this one, and during those two years it is for the provider to prove the add-on conformed, not for you to prove it did not. That comes from EU directive 2019/770, so the right is the same everywhere in the Union; it reaches you through Portuguese Decreto-Lei n.º 84/2021 where the provider is established, and through your own country's transposition where you live.
To use either right, write to the address in section 12. If a purchase is involved, Stripe is the seller under section 5 and its own refund process is usually the fastest route; a statutory claim can be brought against the provider regardless. If it is not resolved, the legal notice sets out the complaints routes that are open to you, including Portugal's free national electronic complaints book.
We may change what Pro includes. We will not remove something you already paid for while your key still works, and section 10 does not entitle us to do so.
The Service itself, including its software, design, branding, name and logo, is owned by its publisher and its licensors and is protected by intellectual property laws. These Terms do not grant you any right to use our branding except as necessary to use the Service as intended.
The free Service is provided "as is" and "as available", and we give no voluntary warranty over it: we do not promise it will be uninterrupted or error-free, or that exports will suit any particular software or workflow. Export relies on browser APIs such as WebCodecs, whose availability varies by browser and version, and a long render is limited by your own device rather than by a server.
The paid add-on is different, and deliberately so. If you bought Pro, you have the legal guarantee of conformity that French and EU law attaches to digital content: it has to match what this page describes, and if it does not you are entitled to have it brought into conformity or to a price reduction or a refund. That guarantee cannot be excluded by anything written here, and nothing here tries to.
To the maximum extent permitted by law, and except where section 7 or the paragraph below says otherwise, Music Waveform and its contributors will not be liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, revenue or profits, arising out of your use of or inability to use the Service.
What is not limited. Nothing in these Terms excludes or limits liability for death or personal injury, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, for a breach of the legal guarantee of conformity owed on the paid add-on, or for any other liability that cannot lawfully be excluded. If you are a consumer, your rights under the law of your country of residence apply in full and this section does not cap them.
The Service is hosted on Vercel and may link to third-party websites or resources. We are not responsible for the content, policies, or practices of any third party. Your use of third-party services is governed by their terms.
We may modify, suspend or discontinue the free Service, in whole or in part, at any time, and we may update these Terms; when we do, the "Last updated" date above changes with them. For the free tool, continuing to use it after a change means accepting the revised Terms.
For the Pro add-on, that is not enough and does not apply. What you bought is what section 5 describes on the day you bought it. We will not remove a feature you paid for while your key still works, and we cannot use this section to do indirectly what section 5 forbids directly. A change that would reduce what Pro gives you does not bind you because you kept using the site; if we ever need to make one, it applies to new purchases.
These Terms are governed by Portuguese law, Portugal being the place where the provider is established — see the legal notice. If you are a consumer, Article 6 of the Rome I Regulation also gives you the mandatory protections of the law of your own country of residence, and nothing here limits them.
If something goes wrong, write to the address in section 12 first. If that does not settle it, the legal notice lists the routes open to you: the free Portuguese electronic complaints book, the consumer dispute bodies available in Portugal and in your own country, and the courts.
Music Waveform is published and operated by Damien Yvert, an independent developer established in Portugal (see About). The provider identification required by article 10 of Portuguese Decreto-Lei n.º 7/2004 — name, address of establishment, email and NIF — together with the seller of the add-on and the complaints routes, is on the legal notice.
