What this covers
Article 50 of the EU AI Act has applied since 2 August 2026; the Act itself entered into force in 2024. Article 50(2) asks the provider of an AI system that generates synthetic audio to mark that audio in a machine-readable way, so it can be detected as artificially generated or manipulated. The duty does not apply to the extent a system performs an assistive function for standard editing, or does not substantially alter the input data it is given. This notice explains how we apply that to Euphona.
The files we deliver
Every Euphona service works on a recording you upload: it masters it, separates it into parts, repairs it, tunes it, mixes it or places it in space. None of them creates a song, a voice or a sound from a description. Labelling is aimed at audio that an AI system generates, and we have reviewed this with our legal advisers. The files we deliver, and the previews you hear, therefore carry no AI label: no tag in the file and no watermark in the sound.
Until the date at the top of this notice, our files carried a machine-readable tag saying they had been processed by machine. Files you downloaded before then still contain it. It does nothing except say so, and you may remove it or leave it.
Where we say machine learning is used
We do not hide that machine learning does the work. The pages that describe each service say what the engine does, and where a model makes an estimate, such as the split between a voice and its backing in the vocal remover, the page says so. The result screens no longer carry a separate notice about it.
If we ever generate audio
If we add a service that generates audio, such as making music, a voice or a sound from a description, we will update this notice before that service launches, including whether and how its output is labelled.
What is true today
Six capabilities are available in the Studio: mastering, stem separation, audio restoration, vocal tuning, mixing and spatial audio. The vocal remover and the demos on this site run the same engine. None of them adds an AI label to what it delivers.
