Investigating Codec-Internal Latent Audio Watermarking for Neural Codec Robustness
Zi Hu, Houmin Sun, Linxi Li +4
Neural audio codecs are challenging transformations for audio watermarking because they re-encode, quantize, and resynthesize speech. This paper investigates continuous latent-spac…

Making Separation-First Multi-Stream Audio Watermarking Feasible via Joint Training
Houmin Sun, Zi Hu, Linxi Li +4
Modern audio is created by mixing stems from different sources, raising the question: can we independently watermark each stem and recover all watermarks after separation? We study…
