This paper presents an improved technique to hide information in audio based on echo modulation. The improvement is done by using a sequence of random binary numbers and by modifying the formula used for adding echo. The experiment shows that our method is more security while still remains the inaudibility of stego audio file and suitable for hiding data in audio.
