Steganography is that the limit and examination of encompassing lined messages during a perspective that no one, nearby the sender and foreseen beneficiary, interfaces the part with the message, a kind of security through nonattendance of clearness. A lot of work has been developed for audio steganography. But there are various problems in the existing techniques. Existing frameworks utilize just word reference-based pressure method which can be supplanted by the mixture pressure systems to accomplish progressively precise outcomes. Existing frameworks have low SNR values which must be improved to utilize the framework in real circumstances. In the proposed work we have used the I-LSB Technique and Adaptive Huffman Compression Technique on audio signals to obtain secure stego-signal. I-LSB uses three bytes of the audio signal to hide the text data. The results are improved as compared to the existing approach which reflects that the new approach is better in terms of security and speed in data transmission.
