Performance Analysis & Evaluation at Wav Audio File in Steganography Using Tone Insertion Technique

Abstract

Wave steganography is focused in hiding secret information in an innocent cover audio file or
signal securely and strongly. Communication security and robustness are vital for transmitting important
information to authorized entities, while denying access to not permitted ones. Existing audio
steganography software can embed messages in WAV, AU, and even MP3 sound files.
With the this technique we have calculate the result of frequency fluctuation at the time of text
embedding. Basically we user frequency modulation for decrease sound movement after embedding text
message in wave file
