Abstract

 
This paper discusses basics of audio watermarking and the concepts of Quantization Index Modulation (QIM), Singular Value Decomposition (SVD), μ-law and their benefits that are useful for watermarking of audio signals. Survey of some related papers discusses the usefulness of QIM technique when used with Discrete Wavelet Transform (DWT) or SVD technique and improvement in DWT based technique using Logarithmic Quantization Index Modulation (LQIM) using μ-law which provides motivation for a new methodology based on LQIM using μ-law to improve SVD technique.

Keywords: Audio Watermarking, blind, QIM, SVD, μ-law

Article published in International Journal of Current  Engineering  and Technology, Vol.3,No.2 (June- 2013)
