voice encryption using matlab
Hi all,
I'm doing a project of voice encryption. The project consist:
1. Record a voice from the PC mic and Encrypt the voice record (rec1) as noise.
2. After encrypt, I need to combine the "noise" with another voice record (rec2), such that it seems to be like a normal voice record (rec2) with some channel noise.
3. Send both sounds (the integrate one) to another user (pc), and the 2nd user need to use a "decoder" to separate the "noise" and to recreate the original voice record (rec1) from the noise.
I dont think it's need to be white noise (I'm right??). I try to add white noise with 'awgn' function - but it still possible to recognize the voice record (rec2).
Could someone can help me with the encryption as noise and how to combine both signals?
Thanx in advance,
Cuchara
