Embedding secret information with song signal may hamper its audible quality as well as originality also would be infringed. Therefore, passing secret code with song signal precisely needs to measure the embedded data volume with song signal within embedding tolerance level. In this paper, embedded secret data with linear coding principles has been applied, enhanced security criteria has been maintained with the help of elliptic curve cryptographic application. Hiding information into audio signals and audible quality is maintained only by calculating the acceptance ratio of embedding data using human perception, modulation of channel capacity in modified form is used to determine the embedded data and song signal trade-off ratio for getting future guideline embedding information in song signal with correlation among embedded data is fabricated. A comparative study has been made with similar existing techniques for performance analysis and experimental results are also supported with mathematical formula based on Microsoft WAVE (".wav") stereo sound file.
