- This work extends our previous research in . This work showed the imperceptibility of audio watermarking system with Bose-Chaudhuri-Hocquenghem (BCH) code, Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) methods. Watermarked image is embedded in the audio host signal accompanied by several attacks. The audio watermarking performances show that perceptual quality of audio with attacks is varies. At quantization spacing of 0.1 perceptual quality can reach -1.55 for level 1 in the audio watermarking system with echo attack. While SNR can reach 10.5 dB in the audio watermarking system with echo attack and BER performance can reach 0.03 in our audio watermarking system also with echo attack. For audio watermarking with equalizer attack the higher the DWT level the better imperceptible and BER performance. While for resampling attack the higher the DWT level the better imperceptible and SNR performance and for echo attack the higher the DWT level the worse imperceptible and BER performance.
