In short
On Naadly, yes: every render carries an inaudible AudioSeal watermark, is served with a header declaring it synthetic, and has a provenance record. It does not change what the audio sounds like, and it is not optional - it is what lets you answer a platform's disclosure field, a broadcaster or a procurement questionnaire.
Three separate things, often confused
- An inaudible watermark - AudioSeal, embedded in the audio itself, survives mp3 encoding and trimming, and is detectable by the matching detector.
- An audible watermark - a spoken or tonal overlay some free tools add. Naadly does not use one; your audio is clean.
- A disclosure - the label you or the platform show a listener. The watermark supports it; it is not a substitute for it.
A watermark is evidence, not protection: it lets you prove which audio came from here, which is what a broadcaster or an ad network asks for. It cannot stop anyone re-recording a speaker through a microphone.
