In this study, we propose a dither modulation audio watermarking algorithm based on human
auditory system which applied the theory of dither modulation. The algorithm made the two-value image
watermarking to one-dimensional digital sequence firstly and used the Fibonacci to transform one-dimensional
digital sequence. Then divide the audio into audio data segment and made discrete wavelet transform with audio
data segment, every segment can adaptive choose quantization step. Finally put low frequency coefficients
transformed embedding the watermarking which applied the dither modulation. When extract the watermark
with no original audio, they realized blind extraction. The experimental results show that this algorithm has
preferable robustness to against the attack from noise addition, compression, low pass filtering and re-sampling.
Key words: Adaptive , discrete wavelet transform, dither modulation, human auditory system, quantization step, ,
