In this paper, an enhancement of LSB audio steganography is presented. This enhancement is based on the mathematical foundations of the magic cube and magic square. Magic cube is a branch of mathematical combinatorics. It is one of the different arrays in magic number arrangements. The proposed technique focuses on normal magic cubes of order (3, 4, … n). The values inside the designed magic cube are used as an index to audio cover locations. These scrambled locations (according to the keys of the magic cube) in the audio cover are used to (LSB) embed secret text message. In order to increase the security of the proposed system, the starting number, the difference value, the dimension, and the values inside the magic cube are kept as a secret key. The NIST package is successfully used to test the randomness of the magic cube's keys values. The PSNR values of audio stego-covers are (62.65743352-79.57336476) dB in which the size of secret text message (256-16) bits.
