Audio watermarking is more inspiring due to the fact that self-motivated control of hearing ability over the chromatic field.Noise is regularly carried to host audio by common signal processing procedure, and it regularly changes the high-frequency component of an audio signal. So inserting watermark by correcting low-frequency coefficient can rise the robustness of a watermark technique. This work proposed a method which embedding watermark into the maximal coefficient in 3rd Level DWT domain. Biased and unbiased tests reveal that the proposed watermarking technique preserves highly audio quality, and concurrently, the algorithm is highly robust to mutual digital signal processing processes. Experimental replications were achieved to calculate the performance of the audio watermarking technique. Audio watermarking discovers applications in the area of copyright, temper discovery and authentication of music’s, military communication, voice activated machines and robots.
