Literature Survey on Audio Watermarking

Adam Brickman EE381K Multidimensional Signal Processing March 24, 2003 Abstract Watermarking audio files has recently become the focus of much attention. This is primarily due to faster data transmission rates on the Internet, which has allowed the often illegal proliferation of digital audio files. Watermarking may give recording companies the ability to enforce copyright protection of their products. The difficulties in watermarking audio lie in both the desire to preserve file quality and the need for the watermark to remain intact after a number of possibly damaging file operations. This article discusses the concepts involved in audio watermarking, applications, previously proposed algorithms and poses a new possibility for a watermarking scheme.
