Robust Audio Watermaking Using Haar Transform

M. Acevedo, J.C. Caravantes, J. L. López, R. Linares


This work shows a robust Watermarking method to be introduced in audio files. The new in this method is the use of theWavelet Haar Transform in combination with Patcwork algorithm in the frequency domain. This combination makes theWatermarking robust against compression, filtering and resampling. We use MATLAB to implement the tests of audiofiles.
