%X The watermarking strength in digital watermarking technology is an important parameter affecting the robustness.Most of watermarking algorithms nowadays make use of experiment to obtain certain the watermarking strength.The results of experiment will be random.So,a lot of experiments have to be done in order to obtain appropriate strength factor.This paper proposed an adaptive audio watermarking strength based on SNR in DCT(discrete cosine transform)domain.Firstly,divided carrier audio into some frames,and ...
