arXiv:2606. 13952v1 Announce Type: cross Abstract: Active Motor Noise Cancellation (AMNC) ships in commercial fused deposition modeling (FDM) 3D printers as a hardware countermeasure against acoustic side-channel attacks that target intellectual property (IP).
The study audits the frequency and decoder‑depth claims of the audio jailbreak AdvWave‑P on the Qwen2‑Audio model. Using a protocol that masks frequency components in the short‑time Fourier transform domain, the authors evaluate attack success across 520 prompts, finding that 76.7% of adversarial inputs are labeled as jailbreaks. Detailed analyses show that masking specific frequency bands can sharply reduce attack success, with finer 16‑band partitions revealing that a narrow 7520‑7960 Hz band is critical, while global rescaling and re‑optimization experiments further illuminate the role of frequency partitioning and energy distribution in jailbreak effectiveness.

EarLog is a real‑time, embedded system that opportunistically uses headphone playback as a probe to detect the acoustic reflex (AR), an involuntary ear response indicating protective activation during high‑load listening. By employing content‑conditioned residual sensing, a resonance‑constrained sparse FIR model, and dual‑microphone observations, EarLog suppresses noise from nonstationary content, individual ear acoustics, and device variations to identify weak AR signals. In a study with 81 participants, 16 headphone models, and over 400 hours of recordings, EarLog achieved 99.0% sensitivity and 98.7% specificity against a clinically referenced benchmark, enabling continuous, listener‑specific AR monitoring during everyday listening.
The study evaluates audio provenance attribution systems, showing that high clean‑benchmark accuracy does not translate to robustness after codec compression. Using a prospectively registered protocol, the authors measured closed‑set attribution performance on two corpora after single‑stage codec transport, finding significant degradation—up to 70.3 Macro‑F1 points for WavLM‑Base+ and 61.0 for W2V2‑BERT 2.0—depending on codec settings and representation. The results demonstrate that clean accuracy alone cannot guarantee deployment robustness across different codecs and representations.
The study explores whether AI‑generated impulsive sounds can be distinguished from real sounds using group delay analysis. It finds that while onset‑region group‑delay distributions are nearly identical, the decay‑region shows a significant divergence (KL = 0.322 vs. 0.022). Various classifiers—single‑feature AUC ≈ 0.720, Random Forest AUC ≈ 0.884, and CNN/transformer models achieving up to 94% accuracy—demonstrate that decay‑region group delay provides strong discriminative power, with Random Forest remaining stable across different STFT settings.
