Abstract

When a digital watermark is directly embedded into low frequency part of audio, sensitive noises maybe occur. In the paper, a method of audio digital watermark based on quantization index modulation is proposed to solve the problem. At first, audio signal is divided to frequency band subsections by audio mask effect. Then low frequency part of discrete wavelet transform (DWT) is extracted. Scramb-ling watermark is embedded into the low frequency part by quantization index modulation (QIM). The experimental results show that the presented method has a good capacity to fight many attacks.
