Meta AudioSeal, read against Article 50
Meta AudioSeal is a speech watermarking scheme published as research rather than as a product feature. The paper describes a generator and detector trained together so that a mark can be located inside a recording, not merely found in it. From 1 source page, read 2026-09-22; no maker pays to be listed.

What Meta AudioSeal publishes, set against the two duties Article 50 imposes. Recorded 2026-09-12.
Point
What the vendor's pages state
Article 50(2), machine-readable marking
An embedded speech watermark, detectable down to the sample
Inclusion rule. Points are the same four for every generator recorded here: the two Article 50 duties, who controls the mark, and whatever the vendor states about it. A point the vendor does not publish is recorded as not documented. Order. Fixed order, identical on every generator page.

2Locating a mark and finding one are different questions
Most marking schemes answer yes or no for a whole file. This one is described as detecting down to the sample level, which answers a different question: which part of this recording was generated. For any audio that mixes a real voice with a synthesised passage, that is the question a listener would actually want settled.
The article does not ask for that granularity, and recording it here is not a claim that it is required. It is worth a row because it shows the ceiling of what a marking scheme can report, and because the duty is written around content that is generated or manipulated, a phrase that plainly contemplates files which are partly one and partly the other.
3A paper is a different kind of source from a pricing page
Every other entry in this record is read from material written to sell or to support a product. This one is read from a publication written to be reviewed, which changes what the sentences are trying to do: they describe a method and the trade-off it makes, and they claim performance against measurements rather than against competitors.
The trade-off named is the interesting part for a compliance reader. A mark has to change the audio enough for a detector to recover it and little enough that a listener does not notice, and the paper puts a loss function shaped by how hearing masks sound at the centre of that. The marking paragraph asks for solutions that are effective and robust as far as is technically feasible, and a published account of where the difficulty sits is closer to that wording than a feature line can get.
Four words is all a row holds. Where a cell read off Meta AudioSeal's research publication needs the sentence behind it, the kind of document that sentence sits in and the limit on what it proves, it is filed on its own page below.
AudioSeal on marking speech — The publication describes a generator and detector trained jointly with a localization loss, for detection down to the sample level.
AudioSeal on detection granularity — The publication presents localized detection at sample level, with a perceptual loss inspired by auditory masking for imperceptibility.
AudioSeal on masking and quality — The publication describes a perceptual loss inspired by auditory masking, presented as achieving better imperceptibility for the embedded mark.
