LATENT-MARK: Robust Audio Watermarking for the Neural Resynthesis Era
Existing audio watermarking fails against modern neural resynthesis due to semantic filtering. LATENT-MARK is the first zero-bit audio watermarking framework designed to survive semantic compression by embedding watermarks directly into the codec's invariant latent space. This approach ensures robust zero-shot transferability to unseen neural codecs, while maintaining perceptual imperceptibility and state-of-the-art DSP attack resilience.

Transformative AI Capabilities for Your Enterprise
LATENT-MARK future-proofs audio intellectual property in an era of advanced generative AI. By embedding watermarks directly within the semantic core of audio, it ensures your content remains traceable and secure, even after complex neural processing.
Stage 1: Cross-Codec Resampling Pipeline
Synchronize heterogeneous codec views by resampling the perturbation to each codec's native rate, ensuring stable optimization across diverse architectures.
Stage 2: Gradient Balancing via Calibration
Calibrate gradients across different latent scales, preventing "gradient dominance" and ensuring equal importance to all codecs in the committee.
Stage 3: Joint Manifold Injection Objective
Minimize a normalized hinge loss across multiple codecs to induce a structurally invariant latent shift, crucial for zero-shot transferability.
Stage 4: Ensemble Detection and A-Score
Aggregate evidence across the committee using a robust median-based scoring mechanism to verify watermark presence and quantify transferability under attack.

Redefining Audio Watermarking for the AI Era
Traditional audio watermarking relies on imperceptible waveform alterations, which modern neural audio codecs, like EnCodec and SNAC, treat as "off-manifold" noise and discard during resynthesis. LATENT-MARK introduces a paradigm shift by embedding the watermark directly into the codec's invariant latent space. This ensures the mark is treated as a structural feature, surviving the semantic bottleneck of neural compression.
The core mechanism involves optimizing the input waveform to induce a detectable directional shift in its encoded latent representation, while ensuring perturbations align with the natural audio manifold for imperceptibility. This "latent-space shift" allows the watermark to persist through the encode-quantize-decode process, remaining detectable even after significant amplitude distortion and phase shifts typical of neural resynthesis.

Unmatched Robustness Across Diverse Attack Vectors
LATENT-MARK demonstrates superior resilience against both novel neural resynthesis attacks and traditional digital signal processing (DSP) distortions, a critical balance for modern content protection.
In evaluations, it achieved survivability scores up to 93% on certain datasets after neural encode-decode passes, a performance where prior state-of-the-art methods typically drop to near-zero. Furthermore, its detectability on unperturbed audio consistently exceeds 95%.

Seamless Transferability Across Codec Architectures
A significant challenge in watermarking is overfitting to a single codec's quantization rules. LATENT-MARK addresses this through Joint Cross-Codec Optimization, where the watermark is jointly optimized across an ensemble of diverse surrogate codecs.
This approach targets shared latent invariants, ensuring robust zero-shot transferability to unseen black-box neural codecs. Evaluations show that architectural proximity plays a key role, with configurations optimized for similar codec families achieving up to 20% higher transfer success. However, even for "distant" codec families, LATENT-MARK maintains a baseline transferability between 50-70%, far outperforming single-codec optimization baselines.
This highlights that embedding watermarks as structural features within the latent space, rather than relying on superficial signal details, is crucial for survival in diverse generative AI ecosystems.
