Convention Paper

Digital Watermarking of Audio Signals Using a Psychoacoustic Auditory Model and Spread Spectrum Theory

Authors: Garcia, Ricardo A.

AES Convention 107 · Paper 5073 · September 1999

Abstract

A new algorithm for embedding a digital watermark into an audio signal is proposed. It uses spread spectrum theory to generate a watermark resistant to different removal attempts, and a psychoacoustic auditory model to shape and embed the watermark into the audio signal while retaining the signal's perceptual quality. Recovery is performed without knowledge of the original audio signal. A software system is implemented and tested for perceptual transparency and data-recovery performance.
