Abstract
An improved digital watermarking algorithm for audio was proposed based on DWT and DCT. Firstly, the binary watermark image which will be embedded to the audio convert signal was pre-processed; and the audio convert signal was divided evenly, the audio segments were selected from the divided audio, then by doing the DWT and DCT embedded the watermark to the low frequency coefficients of those audio segments which were selected; Finally, all of the audio segments were regrouped. The experimental results show that the proposed algorithm is more imperceptible and more robust against to the combinational attack.
