Copyright Protection for WAV-Table Synthesis Audio Using Digital Watermarking

Second IEEE Pacific Rim Conference on Multimedia, Beijing, China, October 24–26, 2001In this paper, we present a novel audio watermarking method for WAV-table synthesis audio (Downloadable Sounds - DLS) copyright protection. In order to guarantee the inaudibility and robustness, we embed watermark both in sample data and in articulation parameters. For sample data, we propose an adaptive low-bit coding method based on finite automaton. For articulation parameters, we generate a virtual instrument and use its parameters to hide watermark information. We also discuss the watermark detection and give the experimental results of watermarked DLS to the listening and robustness tests.Department of Electronic and Information EngineeringRefereed conference pape
