Protect audio with a silent watermark
Silent Watermark is a simple web-based tool that lets you embed an inaudible, tamper-resistant watermark into your audio file. The watermark is undetectable by listeners but can be used to prove ownership or trace unauthorized use.
Adding a silent watermark protects your intellectual property without compromising audio quality. Even if your audio is compressed, trimmed, or edited, the watermark remains intact—making it ideal for music, podcasts, and voiceovers.
Silent Watermark is built for creators and professionals who care about protecting their work:
• Musicians & Labels: Guard against leaks and unauthorized use.
• Podcasters & Broadcasters: Track usage across platforms.
• Digital Platforms: Prevent piracy with invisible tracking.
• Forensic Audio Experts: Embed traceable evidence in recordings.
Just upload your audio, enter your watermark text, and click to embed. You’ll get back a new audio file with your silent watermark baked in. Later, you can verify that watermark by extracting it.
