Abstract—Watermarking has become important in the last
decade because of the copyright protection applications.
Embedding information into an audio file is more difficult as
compared to images because human auditory system is more
sensitive than human visual system. Therefore, the proposed
watermarking algorithms for digital audio have been less than
those for digital image and video. This paper presents a digital
audio watermarking scheme based on spread spectrum
technique to embed the watermark. This method does not need
the original audio carrier signal when extracting watermark
using the blind extraction audio watermark. The experimental
results demonstrate that the embedding technique is not only
less audible but also more robust against the common signal
processing attacks like low-pass filter, adding white Gaussian
noise, shearing, and compression.
Index Terms—Audio signals, spread-spectrum, audio
watermarking, blind extraction.
