This work contributes to the multimedia security fields by given that more protected steganography technique which ensures message confidentiality and integrity. An Advanced Least Significant Bit (ALSB) technique is presented in order to meet audio steganography requirements, which are imperceptibility, capacity, and robustness. An extensive evaluation study was conducted measuring the performance of proposed NLSB algorithm. A set of factors were measured and used during evaluation, this includes; Peak Signal to Noise Ratio (PSNR) and Bit Error Rate. MP3 Audio files from five different audio generators were used during evaluation. Results indicated that ALSB outperforms standard Least Significant Bit (SLSB) technique. Moreover, ALSB can be embedding an utmost of 750 kb into MP3 file size less than 2 MB with 30db average achieving enhanced capacity capability.
