This article describes a new robust method for digital audio signal watermarking, which exploits the MCLT (Modified Complex Lapped Transform). Magnitude components of audio signal in the MCLT domain are exploited for watermark embedding. By adaptive adjustment of the coefficient of robustness such changes in the magnitude of audio signal components are achieved that maximal watermark robustness with minimal distortion of original data is assured.
