A novel approach of audio watermarking based on S‐box transformation

In this letter, we present a new audio watermarking technique using $S$ ‐box transformation. Furthermore, we analyze the strength of the proposed watermarking technique with MSE analysis, PSNR analysis, SSIM analysis, robustness analysis, compression attack analysis, noise attack analysis, cropping analysis and capacity analysis and conclude that the proposed method of watermarking is better than many existing techniques.
