Hi all,
hope all be fine.

first I'm very newbie in DSP so sorry if my questions are stupid :D
I'm working on a project to hide data in an audio file using direct
sequence spread spectrum technique with matlab.
I need to know should i understand the dsss technique in communication
to do that or that's a different task ?
also can any one suggest me any resource to start with?
and what i will need to know before start coding ?

thanks in advance and sorry for disturbing you.
