steganography for audio watermarking

anyone can help me, I'm working on watermarking appl开发者_StackOverflow社区ication for mp3 files with algorithms "echo data hiding". I do not understand to make this algorithm with java or matlab. I hope anyone can help by explaining this algorithm, or give examples with source code.

thank you


Maybe this paper brings some light in the darkness: Watermarking


Binary Universe gives an overview of stenography in general and has a section on audio, although it doesn't deal with mp3. I'm not sure how feasible stenography is for a lossy format such as mp3. I assume you would have to add it after the compression has taken place.
