I found a link on Audio Steganography you may find useful: http://www.terminall...gonography.ppt.

As for giving you the code, that isn't going to happen.

Dream.In.Code has a policy by which we prefer to see a good faith effort on your part before providing source code for homework assignments. Please post the code you have written in an effort to resolve the problem, and our members would be happy to provide some guidance. Be sure to include a description of any errors you are encountering as well.

I've already done a lot of work for my Steganography project,
I'm modifying LSB bits of main mp3 file using the following code.
But all i want from you people is to help me out to identify the frames of mp3 file,so that i can use them to store my message there.
[code]
for(i=0,j=256 ;i<(intMessageSize*8);i++,j++)
{
if ((t[i]==0) && (byteArrayIn[j] & 0x01) ==1)
byteArrayIn[j]= (byte) (byteArrayIn[j] & 0xFE);
else
byteArrayIn[j]= (byte) (byteArrayIn[j] | t[i]);
}
[code/]
where byteArrayIn[] contains the input mp3 file in byte format.
t[] contains the message . it is the array in which except LSB all the bits are o. And LSB contains the message bit.

I'm assuming the byte offset of 256 bits ...nothing special here.
And there i'm storing my bits..
I was already having the document that u referred me to, thanks for that anyways. I read that completely but not able to do it.
Please help me out with a code so that i'll be able to identify ID3v2 header & mp3 frames.
