Steganography that is applied to hide information on the cover of digital objects is called Digital Steganography. Cover objects that are used in digital steganography can vary, for example in the image archive. Steganography algorithms in the image archive has been widely developed. Meanwhile, steganography algorithms in audio archive is relatively few. This paper discusses the application of digital steganography on audio archives using the method of Direct-sequence Spread Spectrum. The author also found relating book and paper that describe the theory about audio steganography using spread spectrum.
