For organisations
The facts you need before you send us audio.
AudioLab.tools measures audio: loudness, true peak, voice quality and a timeline of speech, music, noise and silence. It does not judge what is said. This page puts in one place where your audio goes, how the numbers were checked, and how to work with us.
AudioLab.tools is run by AudioLaunch (KvK 54871204, Eindhoven, the Netherlands) and built by Nathan Renting, a working audio developer. It is self-funded, without investors. You contract with AudioLaunch under the terms, and Dutch law applies.
- In the browser labs, nowhere. The audio is analysed on your own device and sends us nothing. The one exception is HearLab’s live captions, which use your browser’s speech recognition.
- Through the hosted API or the MCP server, the audio is decoded and measured inside the request and is not kept; a compressed file passes through temporary scratch space that is deleted as soon as decoding is done. On the signed-upload route, for larger files, the file lands in EU storage for a moment and is swept within the hour.
- In the EU. The functions that measure audio run in the EU (Vercel, region fra1); the database and the upload bucket are in Frankfurt (Supabase, AWS eu-central-1).
- Only for you. We do not use your audio or your results for our own purposes: not to improve the engine, not to train models, not for advertising. We do not sell or share them.
- What we keep. Measurements and metadata (the tool, the duration, a few numbers, and the file name if you did not choose to anonymise it) stay for your history and your usage limits until you delete them or your account.
The data processing addendum (Article 28 GDPR) is part of the terms from the moment you send personal data: you are the controller, we are the processor. We report a breach within 48 hours of discovering it, announce a new sub-processor 30 days ahead, and cooperate with an audit by an independent expert. The addendum has a section in Dutch. The privacy page lists what each part of the site stores.
Loudness is checked against the signals the EBU Tech 3341 and 3342 standards define, and lands within 0.06 LU in the worst case; every case is published on the API page. A reverb score that failed a check against 24 rooms was withdrawn, and the methodology page lists what else we got wrong.
A browser or a phone is not a calibrated lab instrument. NoiseLab is a first scan, not a class 1 or class 2 sound level meter, and RoomLab is a quick check, not an ISO 3382 measurement. A formal assessment still needs a competent person.
Free, Plus and Studio are self-serve on pricing, with a free tier of 1,000 calls and 2 GB a month and no card. Enterprise is on request: from €499 a month, with an SLA and dedicated support and a self-hosted licence option.
VeldLab, a Windows program for organisations that run measurement days, is delivered under Enterprise and priced per use case. Its software side is complete for its first milestones; validation on reference hardware is the open step before a wider rollout, and pilots run with that stated.
