afaik, audio cryptography and non-binary audio cryptography
have been investigated by Desmedt, Quisquater et al. in the last years.

the fundamental bibliography and references is the following:
Yvo Desmedt, Tri Van Le, Jean-Jacques Quisquater: Nonbinary Audio
Cryptography. Information Hiding 1999: 478-489
Audio and Optical Cryptography. In K. Ohta and D. Pei, editors,
Advances in Cryptology - Asiacrypt '98, Proceedings (Lecture Notes in
Computer Science 1514), pp. 392-404. Springer-Verlag, 1998. Beijing,
China, October. Y. Desmedt, S. Hou and J.-J. Quisquater.
