Abstract
AbstractAn audio watermarking scheme in wavelet domain which takes advantage of substitution is proposed in this paper. First the host audio is decomposed by wavelet transform, and then convert low frequency coefficients to segments. Finally embed the watermark XOR with a pseudo-random sequence into the host audio by substitution of the segments. The experimental results illustrate that the suggested scheme has achieved high imperceptibility and is robust against common audio signal processing such as addictive noise, low-pass filtering, median filtering, re-quantifying and re-sampling.Keywordsaudio watermarkingwavelet transformpseudo-random sequencesubstitution
