RE: [WM]: Audio Watermarking using Least Significant Bit Coding

["Kourosh Fallah" <kourosh@ics.mq.edu.au>]

Hi Ellias,

Try using bitset(a, bitPosition, bitValue) where a is your data matrix. This will change the desired bit in all elements in one go.

Dec2bin(a) should do the displaying job.

Subject: [WM]: Audio Watermarking using Least Significant Bit Coding

Dear fellow watermark fanatics,
   
  I am writing to request any ideas about how to go about carrying out a watermark on an audio signal using least significant bit
coding. I can manage to convert the wav sample in MATLAB into an MAT format so that i can carry out different processes on it.
  Would any of you reckon a 'for statement' to set every so many bits using the 'bitset' function?
  How can the actual values of each sample be displayed in binary?
   
  kind regards,
   
  Ellias
