As i do some research on watermarking on audio i firstly wanted to insert some text to the audio signal, i just read a way to do it. But before that i need to do DSSS( Direct Sequence Spread Spcetrum) to my watermark data in my case text/char after the text/char was converted to binary. Any suggestion how i can get started? Or is this even possible?
Well i got the information here
http://www.ijcaonline.org/volume24/number1/pxc3873842.pdf
I read the embedding process, step 1 it say that we need to spread the watermark data with DSSS. Anyone can give me some advise?
My Case here asumme that i have this text : test -> convert to binary -> 01110100 01100101 01110011 01110100, how can i apply DSSS to this binary data?
