This article decribes an audio watermarking algorithm based on statistical methods working in the fourier domain. It presents a solution of robust watermarking of audio data and reflect the security properties of the technique. The article includes MATLAB code to embed watermarks and retrieve them from audio data to prove the presented concepts. Enhancements of the presented methods are discussed.
