Audio Steganography Project

Check the attached documentation its the same as here but better formatting.

I want the "same" program in matlab or java that i linked here: c#

Main goal:

The program needs to embed a message in an audio file into the analog signal. And also extract from the analog signal.

Algortihm:

You can check this. Its written by c# but I need it in Matlab.

The program need a graphical interface, which contains the following functions ( and graphs )

Functions:

1. embedded function : essential

o Input:

 file: audio

 string message

o output

 file:audio ( with the embeded message )

2. extract function essential

o intput (a):

 file: audio

o input ( b)

 microphone audio stream optional

o output:

 string message

3. Play essential

o input

 file: audio

o play the input audio

4. Show graph essential

o input

 file: audio

o show the analog signal of the audio file

5. Pitch detection ( Noise detection) essential

o input

 file:audio

o show the lines where’s the possibly beacons

Sample code in c# should works like :

So I enter the message, then calculate the length. If it ok then embed the message

The extractor filter the „unnecessary” signals and calculate distances and returns with the message.

Documentation:

All function, how they work and why.

And source where you find the libraries and the documentation why you do that way etc.

(with links if possible if not only a small description )

I have devoted my last years of research and work to signal processing, specially image processing but also 1D signals. In addition, I feel totally at ease with Matlab programming.
