| 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. | ||
