This paper proposes a novel model to hide the very secret and sensitive information within an audio file. The proposed model consists of three stages, the text is first compressed using the Huffman algorithm then encrypted using AES algorithm and finally hide using the novel LSB-Block algorithm. A novel proposed mechanism, Binaries of Message Size Encoding (BMSE), were performed before the hiding process to produce a key, which is used in the hiding process in the proposed enhanced LSB-Block algorithm. The model was applied using the MATLAB program and tested using the Mean Error Square (MSE) operators and the Peak Signal to Noise Ratio (PSNR). Different comparisons were made and the results verified the efficiency and effectiveness of the proposed model.
