In this paper, a high capacity digital audio reversible watermarking algorithm based on generalized integer transform is proposed. The proposed algorithm is built on top of a recently proposed reversible image watermarking scheme. The main challenges to customize an image watermarking scheme to work for audio domain are the differences between the structures of image and audio, the target of the scheme based on is a two-dimensional 8-bit grayscale image and the target now is a one-dimensional 16-bit quantization audio waveform. The dimension issue can be solved by small modifications, to partition the audio waveform into two portions, so that the image watermarking scheme based on can be applied to the audio. For the proposed algorithm, satisfactory amount of data can be hidden into the audio and the stego audio is perceptible for large payload but not annoying for listening.
