We use s = { s ( i )|0 ≤ i ≤ N − 1} to denote one frame of host audio signal of length N. The SS sequence q is a pseudo-noise (PN) sequence generated by the embedding/extracting key. m = { +1, −1} is the bipolar binary watermark information. Then the basic model of SS watermarking can be shown as.

In this paper, a frame based audio watermarking scheme using spread spectrum technique in time domain is proposed. The algorithm consists of two procedures; watermarking . embedding procedure and watermarking extraction . procedure. respectively. The watermarked image is M×N pixels. The audio that watermark is embedded is a wav file.
Secure Spread Spectrum Watermarking For Multimedia - …

watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i.i.d.) Gaussian random vector that is imperceptibly inserted in a spread-spectrum-like fashion into the perceptuallymost signifi-cant spectral components of the data.

In this project, a simple watermarking system for spread spectrum audio is developed using the FFT transformation to insert the data into the signal host. The system is designed to resist the problem of desynchronization using synchronization codes.

Originally applied to images, spread spectrum watermarking has gained wide usage in all types of digital media, including audio and video. The second was written by Ernst Terhardt in 1981, and describes a psychoacoustic model for determining how salient a pitch is to the human ear, given a frame of audio data.
