Robustness of One Bit Per Sample audio watermarking

One method of audio watermarking is to embed one bit of the watermark in each sample of host signal. The watermark bit can be embedded by replacing the least significant bit (LSB) or bit at a higher layer of host signals. We shall refer to this method as one bit per sample (OBS) approach. In this paper, the robustness and performance of one bit per sample (OBS) approach is reported. Different forms of attacks are imposed on the watermarked signals. For the attack from noise, white noises of different magnitudes are added. Different audio signals including music and speech are used for the assessment.
