Nonoisy
Nonoisy is a browser-based audio post-production service for recorded speech. Upload any audio or video file and its algorithms strip background noise, master the track and level the volume, returning the same format for EUR 5 per hour.
What is Nonoisy?
Nonoisy is a web service that automates audio post-production for recorded speech. The scope is deliberately narrow: you create an account, upload an audio or video file in whatever format you happen to have, and the service returns the same format with the sound cleaned up. Three treatments are applied and repeated across every page of the site, namely background noise removal, mastering and volume levelling. Processing starts as soon as the upload completes, and a progress indicator tracks the job.
What sets the boundary is the word spoken. Nonoisy is built for speech rather than music, and it claims to be language-independent because it works on the sound signal instead of the words. The problems it names are the ordinary ones of unmonitored recording: hiss and electrical hum, traffic and wind, background chatter, plosives and sibilance, a dog barking, and speakers sitting at different volumes because one of them is further from the microphone.
The application behind the login is more complete than the marketing pages suggest. An upload page takes the file, an optional Remove silences toggle and a start and end trim expressed in seconds. A history panel lists previous uploads with their name, date, duration, status and format, and allows each one to be downloaded again. Most usefully, a waveform editor lets you select a region and choose between the de-noised version and the original, which is the standard remedy when an automatic de-noiser has eaten an intro jingle or a wanted ambience. A settings page shows the credit balance in hours and seconds, and a payments page tops it up.
Pricing is unusually plain. The first test minute is free with all functionality included, and beyond that processing costs EUR 5 per hour of media, bought as prepaid credits rather than a subscription. Larger archives are handled by arrangement, with transfer and delivery organised directly. What the site does not provide is any corporate or legal framing: no company name, no address, no terms and no privacy policy.

When to use Nonoisy / When not to
A quick filter to help you decide if Nonoisy is the right fit.
When to use Nonoisy
- Podcasters who record remote guests and have no sound engineer to clean up the result
- Video creators and course makers whose picture is good but whose audio lets the production down
- Journalists and interviewers working with field recordings made in noisy, uncontrolled places
- E-learning and instructional design teams producing large volumes of narrated lessons
- Anyone holding a large archive of spoken recordings, since bulk work is arranged directly rather than uploaded file by file
When not to use Nonoisy
- Music producers, since the tool is built for spoken audio and works on speech rather than musical material
- Organisations needing a signed DPA or a documented GDPR position, because no contractual document is published at all
- Teams wanting to automate a pipeline, as there is no API, no SDK and no integration of any kind
- Audio engineers who want parameter-level control, the only settings being a silence toggle and a start/end trim
- Anyone needing a mobile or desktop app, or multi-user collaboration, none of which exist

Data, GDPR & hosting
A consolidated view of how Nonoisy handles your data.
GDPR overview
There is no GDPR framework of any kind on this site, and the distinction matters: Nonoisy does not decline compliance, it simply never addresses the subject. No privacy policy, no terms, no legal notice, no cookie policy and no consent banner exist, and the words GDPR and data protection appear nowhere. No controller is named, no data protection officer is designated, and no Article 27 representative is given. Google Analytics loads on the home page before any consent is sought or any information offered. The service is plainly aimed at Europe, with prices in euros, a Dutch registrar and servers resolving to the Netherlands, which makes the omission more consequential rather than less. The N recorded for GDPR compliance reflects total silence, not a stated refusal.
Who owns the data?
Nothing can be reported here, and the reason matters. Nonoisy publishes no terms and conditions, no privacy policy and no legal notice anywhere on the site; this was verified against the sitemap and against the application's complete routing table, so it is a confirmed absence rather than a link that was missed. Nobody is therefore told who owns an uploaded recording, what the operator may do with it, or which third parties might receive it. Users keep whatever rights they held before uploading, but they receive no contractual commitment in return. Where the recording features identifiable third parties, that silence is the central difficulty.
Reuse rights
The site is equally silent here. With no terms of service there is no licence grant, no reuse clause and no statement of what either party may do with a processed file. In practice a user downloads the cleaned version of a file they uploaded themselves, so ordinary ownership applies by default, but nothing is written down and nothing confirms that the operator claims no further use. No statement covers whether uploaded recordings are used to train models, and no opt-out is documented.
Data retention & training
Hosting summary
No hosting information is published. The site names no data centre, no hosting provider, no country and no jurisdiction, and since there is neither a privacy policy nor terms of service, there is no document in which such a statement could appear. What can be observed from outside is that the domain resolves to an IP address geolocated in Lelystad, in the Netherlands, on a Dutch hosting network, and that the domain itself is managed through a Dutch registrar. That is a network observation rather than an undertaking by the operator: it says where the web server answered on the day of the review, not where uploaded files are stored, replicated or backed up, and it carries no commitment to keep them in that jurisdiction. Anyone who needs a guaranteed hosting location, or a contractual data residency clause, will find nothing here to rely on.
Things to keep in mind
Risks and trade-offs to weigh before adopting Nonoisy.
- No terms of service and no privacy policy exist anywhere on the site, so uploading a file is done without any contractual protection whatsoever
- Uploading recordings of identifiable third parties, such as interviews, clients, patients or support calls, exposes the user to GDPR obligations that no DPA is available to cover
- Nothing states how long files are kept, where they are stored or how to have them deleted, yet the upload history shows they persist on the server
- No indication is given as to whether uploaded recordings are used to train models, and no opt-out is documented
- The operator is anonymous: no company, no address, and a personal Gmail address as the only contact, for a service that takes prepaid payments
- Google Analytics runs from the home page with no consent banner and no cookie information
- The site has not visibly changed since 2022 and one page still carries content from an unrelated product, so buy credits in small amounts and confirm the service still runs first
Setup & Integrations
Technical difficulty
Very low, and this is the central selling point. Nothing is installed, no plugin is needed, no API key is issued and nothing is configured. Three steps cover it: create an account, upload a file, download the result. The only settings exposed are a Remove silences tick box and a start and end trim in seconds. The optional waveform editor asks you to read a waveform and pick a region, which is slightly more involved, but it can be ignored entirely. No audio engineering knowledge is required at any point.

Should you pick Nonoisy?
Nonoisy does one thing and does it plainly: it takes a recording of people talking and gives it back cleaner, evenly balanced and consistent from beginning to end. For a podcaster with a remote guest, a lecturer recording a course, or a journalist back from a noisy street, that solves a real problem without buying plugins or hiring an engineer. The product is demonstrably there: before-and-after samples play on the site, pricing is public and specific at EUR 5 per hour with the first minute free, and the signed-in application includes a waveform editor that undoes over-aggressive cleaning on a chosen passage, which is the feature this category most often lacks.
The reservations concern not the software but who stands behind it. No company is named anywhere. There is no postal address, no terms of service, no privacy policy and no cookie notice, and the only contact is a personal Gmail address on a product page, for a service that takes prepaid payments in euros. Nothing states how long uploaded files are kept, who owns them, or whether they are used to train anything. The copyright still reads 2022, one route serves leftover boilerplate from an unrelated appointment-booking template, and analytics load without consent.
The practical line is easy to draw. For personal projects and non-sensitive content, Nonoisy is a cheap, fast and genuinely useful tool, and the free first minute costs nothing to test. For recordings of identifiable third parties, such as interviews, clients, patients or support calls, and for any organisation that must document its GDPR position, the absence of a single contractual document is disqualifying whatever the audio quality. Buy credits in small amounts, and check the service still runs before committing further.
