Variable-dimensional vector modulation for perceptual-based DWT blind audio watermarking with adjustable payload capacity
TLDR
The effectiveness of the proposed VDVM scheme is proven using the perceptual evaluation of audio quality and bit error rates of recovered watermarks under various signal processing attacks and the imperfection of applying quantization index modulation in the open-loop case is rectified.About:

Quantization index modulation: a class of provably good methods for digital watermarking and information embedding
Brian Chen,Gregory W. Wornell +1 more
TL;DR: It is shown that QIM is "provably good" against arbitrary bounded and fully informed attacks, and achieves provably better rate distortion-robustness tradeoffs than currently popular spread-spectrum and low-bit(s) modulation methods.

Transform coding of audio signals using perceptual noise criteria
TL;DR: A 4-b/sample transform coder is designed using a psychoacoustically derived noise-making threshold that is based on the short-term spectrum of the signal, and tested in a formal subjective test involving a wide selection of monophonic audio inputs.

Perceptual coding of digital audio
T. Painter,Andreas Spanias +1 more
TL;DR: This paper reviews methodologies that achieve perceptually transparent coding of FM- and CD-quality audio signals, including algorithms that manipulate transform components, subband signal decompositions, sinusoidal signal components, and linear prediction parameters, as well as hybrid algorithms that make use of more than one signal model.
