[WM]: audio watermarking using perceptual masking

[Ellias Militsis <eliado85@yahoo.co.uk>]

Dear All,
  
  I am writing this is to ask if anyone has any idea about how to go  about implementing psycho acoustic masking and noise shaping
in audio  watermarking in MATLAB and also a detection scheme that would  correspond to that. 
  
  Also if it is possible to also get an algorithm for segmenting the  audio in MATLAB to carry out the necessary process. If anybody
could  please help me out here, I would greatly appreciate it.
  
  Yours Truly,
  
  Ellias
