The major concern to authenticate an audio signal is restoring its basic audible properties and providing such a way that may not produce any unusual perception to listeners.Therefore, authenticating an audio signal needs to embed as less as minimum security code within tolerable range of perception.In this paper, perceptual encoding has been applied for structuring song signal in a specified manner with less modification of its amplitude values and followed by embedding formatted data in skewed pattern that will use for verifying any type of alternation by comparing its own structural format and systematic structure of song signal with neighbouring sampled values.A comparative study has been made with similar existing techniques and experimental results are also supported with mathematical formula based on Microsoft WAVE (".wav") stereo sound file.
