Best,

Hello Mr Tekeli, i was evaluating the improved Spread spectrum (2).Its really works well.Wanted to know the major difference between Spread spectrum 1 and 2 and also part of the code in improved Spread spectrum (2) ,iss_improve.p, which is obfuscated. Can i get the code for iss_improve.p ?

I would like to know if it is possible to modify MATLAB code to perform processing of multiple audio files at once? At the moment I'm having trouble using ECHO hiding with single kernel to embed the same information for multiple tracks.

The program works well! But I have a question to ask you, is if I want to join the common noise attack, this audio file will be damaged, can not recover, how to solve this ？Have a nice day!

Hi, I'm Faruq, I just tried your code, the code really awesome, I want to ask, is it possible to use your code in the encrypted file such the enrypted file from docx file that I've encrypted first? I tried echo data hiding in single kernel btw.
Thank You

When trying to run a script using octave, I get this error:

line 1: /mp3bin/mp3info.x86_64-pc-linux-gnu: No such file or directory

Those seem to be missing in all mp3bin directories.

Is this project supposed to be run on Windows or MacOS instead?

Hi! Thank you for your implementation which helps me a lot!
You use filter function to generate echo signal echo_zro and echo_one in echo_enc_single.m from line 43 to line 47.

k0 = [zeros(d0, 1); 1]*alpha;        %Echo kernel for bit0
k1 = [zeros(d1, 1); 1]*alpha;        %Echo kernel for bit1
echo_zro = filter(k0, 1, signal);    %Echo signal for bit0
echo_one = filter(k1, 1, signal);    %Echo signal for bit1

However, it seems more likely to be time spread method from Kadir's thesis in page 83.
The actual single kernel method's computation maybe should be:

echo_zro = [zeros(d0,s.ch);signal(1:end-d0,:)]*alpha;
echo_one = [zeros(d1,s.ch);signal(1:end-d1,:)]*alpha;

Is my understanding right?
