Audio Steganography

Audio Steganography, how does it work?

In Abstract: The process of hiding file (audio, text, picture, ….) into an audio file. The Stego application hides the file you want to encrypt in the audio file you want to encrypted into it. And if you want to decrypt that file and returned it the Stego App will reverse the process and return it.

How can one create hidden text messages in audio files? How can one remove them?

To encrypt text file you have some options, i recommend the first one (The easiest and efficient one):

  1. LSB Coding: just convert your audio file into binary numbers and replace its least significant bits with the bits of the text file (in binary format).
  2. Spread Spectrum.
  3. Echo Hiding: add echo to the audio.
  4. Parity Coding: deals with bits like the first but it’s more complex.
  5. Phase Coding: works by replacing the reference phase of an audio segment with a reference phase of the text and make some operations.

What are some working examples that show this process on the Internet?
