Abstract

Spread spectrum Audio watermarking technique based on SNR (signal to noise ratio) is implemented in wavelet-DCT domain. The technique is developed for blind detection of the watermark. To check the robustness of the technique the watermarked signal is passed through different signal processing attacks and is observed that the watermark remains present after all signal processing attacks. The technique is also tested with the subjective listening test and it is confirmed that the there is no perceptible difference between the watermarked signal and the original host audio signal.
