Summary:
In this paper, we aim to improve the sound quality of the audio watermarking method using smearing transformation, which is proposed by M.Wakai et al. Since noise is caused by the signature impulse, we aim to reduce the power of the signature impulse. In our method, the signature impulse is filtered by low-pass filter, and then the filtered impulse is embedded.
