4) Frequency hopping spread spectrum technique is used. Hopping sequence is necessary for this purpose. Length five hopping sequence is created where every element of this sequence is an integer between 1-8. This sequence will tell us which bit to embed the watermark. ‘n’ means embed the watermark to the nth least significant bit.
Robust frequency hopping and direct sequence spread ...

Audio watermarking is a more challenging task because it is more easily detected. This paper presents a digital audio watermarking scheme based on frequency hopping spread spectrum technique on wavelet domain to embed the water-mark. Before embedding, the watermark is spread with the Direct Sequence Spread Spectrum (DSSS) technique.

the frequency spectrum are significantly more susceptible to at-tack noise. That reduces the effective watermark length because the inaudible portion often dominates the frequency spectrum of an audio signal [6]. In order to quantify the audibility of a particular frequency component, we use a simple PAFM model [16]. For each MCLT
