| Abstract(in English) | In this paper, we discuss about optimization of the parameters such as block size in orthogonal transform, quantization step, and frequency parameter, for digital audio watermarking. We treated watermark method which embedded information by modified coefficients on frequency domain. We evaluated survivability of the embedded information after lossy compression (MPEG1 LayerIII,Twin-VQ). As a result, we found some optimized frequency domain coefflcients for watermark different from image watermarking case. |
