Exploiting Neural Audio Codec Latents for Adversarial Audio Attacks

Researchers demonstrate a novel adversarial attack method against audio classification systems by operating in the latent space of neural audio codecs, achieving 99% attack success rates with extremely low inference latency (sub-7ms). This approach significantly outperforms existing generative and optimization-based attack methods, revealing critical vulnerabilities in real-time audio security systems like speaker verification.

A Projection-Based Surrogate Gradient Interpretation for Neural Codec Wrappers

Researchers propose a new interpretation of surrogate gradients for training neural codec wrappers, showing that the SCALED method can be understood as a first-order approximation of video codecs. The technique enables end-to-end learning of pre- and post-processing networks alongside conventional codecs, achieving significant compression improvements of up to 23.59% BD-Rate reduction on x264.

Feature-Aligned Speech Watermarking for Robustness to Reconstruction Distortions

Researchers propose a feature-aligned speech watermarking method that embeds imperceptible identifiable information into audio while maintaining robustness against speech reconstruction models. By aligning watermarks with original speech feature distributions, the technique overcomes the traditional robustness-fidelity trade-off that has limited previous audio watermarking approaches.
