2. DISCRETE WAVELET TRANSFORM BASED AUDIO WATERMARKING The basic idea in the DWT based watermarking is time-frequency decomposition of the signal using suitable wavelet and embedding the bits corresponding to the watermark image into the wavelet coefficients. The basic scheme of digital
Blind audio watermarking based on discrete wavelet and ...
https://ieeexplore.ieee.org/abstract/document/7150750
In this paper audio watermarking scheme is proposed using Arnold transformation with discrete wavelet and cosine transform. In audio watermarking, embedding is done by going sufficient level of approximation of audio signal using DWT and packetizing approximate function, then taking DCT where scrambled watermark image is embedded. …

Discrete Wavelet Transform Wavelet Transform is a modern technique frequently used in digital image processing, compression, watermarking etc. The transforms are based on small waves, called wavelet, of varying frequency and limited duration. A wavelet series is a representation of a square-integrable function by a certain
