This is my the code for MSc's thesis: a steganographic system for Vorbis audio streams.
It was coded about 10 years ago. I just recalled it and thought of uploading it here for archival purposes. Use at your own risk.
If I remember correctly, my actual code is mostly inside the steganos folder.
For details, check my MSc thesis "Steganography and Steganalysis: Data Hiding in Vorbis Audio Streams."
