“…Therefore, protection methods are required to meet some demands in the multimedia copyright including image, audio, and video files [1,2]. Some watermarking many studies have been conducted in various methods, such as time [1], temporal [2], DCT (discrete cosine transform) [3,4], DWT (discrete wavelet transform) domain methods [5][6][7]. By adding SVD (singular value decomposition) in the DWT based audio watermarking method, authors in [8][9][10][11] showed that the system has a high performance.…”

This study is an extension of a recently conducted study in audio watermarking system. This study shows the imperceptibility of audio watermarking system based on 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, objective difference degree (ODG) can reach -1.55 for level 1 in the audio watermarking system with echo attack. While signal to noise ratio (SNR) can reach 10.5 dB in the audio watermarking sistem with echo attack and bit error rate (BER) performance can reach 0.03 in our audio watermarking system also with echo attack. However, the audio watermarking system with equalizer attack shows that the higher the DWT level, the better imperceptible and BER performance is. Different from that of the system with equalizer attack, the watermarking system with resampling attack shows that the higher the DWT level, the better imperceptible and SNR performance is.
