Original Abstract Submitted

a method for embedding audio payload in audio content, a method for decoding audio payload embedded in audio content, and a method for detecting transients. complementary spreading sequences are used in direct spread spectrum watermarking or alternatively using multi-level spreading sequences applied to modulate the amplitude spectrum of the audio content to embed the payload by spreading the payload bits. decoding watermark bits based on correlation sign or decoding by obtaining a number of windows used during encoding to combine the amplitude spectra into one window for calculating the correlation with at least spreading sequence. encoding and decoding a payload by using multiple windows combined with different polarities as a block to transport the same payload.
