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.

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 )

Hello! I can complete the project in Matlab in 5 working days. I start working on the project as you select me as provider. I will deliver the code as you create the requested milestone. Regards, Botond
hello, sir i am expert in matlab. i have a lot of experiences following fields. Fuzzy Logic Contoller, PID, FNN, Wavelet, image & video processing, PDE, Neural Network, Genetic Algorithm, Simulink,DSP, Math, Physic 更多
i will make GUI and perform require work . . ................ .. PM. .. . ..................................... . . .
i have done my project in matlab for eeg signal processing so i am confident that i can easily do ur project
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.
