This paper presents an encryption technique for the audio which is applied at the time of compression. Encryption algorithms are used to provide security to the multimedia data. Here, Advanced Encryption Standard (AES) encryption is applied on the quantized audio data which is performed before the Huffman's entropy coding. Experimental results demonstrate that AES encryption technique provides high security against cryptographies attacks. Here, the authors have applied the AES encryption technique to different audio files and its utility in the real time systems.
