Data Hiding in Audio Wave File Data Hiding in Audio Wave File

Abstract
Perceptual audio coding has become a customary technology for storage and
transmission of audio signals. Watermarking enables the robust and imperceptible
transmission of data within audio signals, thus allowing to attach valuable information to
the content, such as song title, name of the composer and artist or property rights related
data [1].
This paper presents improved LSB (least significant bits) algorithm for
embedding a watermark of text type in wave audio file. From Experimental results in this
paper conclude that the improved algorithm gives the robust by repeating the watermark
on the cover file and gives imperceptible for lessener so there is no noticeable difference
between the original and watermarked file, testing to check that there is no noticeable
difference between original and watermarked wave file depending on the watermark bit
error rate measurements.
