Audio Watermarking
A technique for embedding imperceptible identifying information into audio signals, used for copyright protection, content provenance, and deepfake detection. Evaluation metrics include imperceptibility, robustness, and capacity.
Timeline (last 90 days)
An overview of synthetic content risk controls published by NIST notes that a single detector or watermark is insufficient to reliably prove audio authenticity, that watermarks may fail due to compression, resampling or malicious attacks, and that metadata can be stripped or forged.
Audio watermarking and provenance metadata (such as the C2PA standard) are two concepts often confused in synthetic content governance: watermarking refers to embedding an imperceptible signal in the audio waveform for later detection, while provenance metadata records the content's generation history and editing chain at the file level.
Audio watermarking can be divided by embedding method into three categories: time domain, frequency domain, and perceptual domain.
The three metrics for evaluating an audio watermarking scheme are imperceptibility, robustness, and capacity.
The core contradiction of TTS watermarking technology is the trade-off between watermark robustness and speech quality.
