ABSTRAKPenelitian ini mengembangkan teknik Compressive Sensing (CS) untuk audio watermarking dengan metode Lifting Wavelet Transform (LWT) dan Quantization Index Modulation (QIM). LWT adalah salah satu teknik mendekomposisi sinyal menjadi 2 sub-band, yaitu sub-band low dan high. QIM adalah suatu metode yang efisien secara komputasi atau perhitungan watermarking dengan menggunakan informasi tambahan. Audio watermarking dilakukan menggunakan file audio dengan format *.wav berdurasi 10 detik dan menggunakan 4 genre musik, yaitu pop, classic, rock, dan metal. Watermark yang disisipkan berupa citra hitam putih dengan format *.bmp yang masing-masing berukuran 32x32 dan 64x64 pixel. Pengujian dilakukan dengan mengukur nilai SNR, ODG, BER, dan PSNR.

本研究开发了一种压缩压缩技术,采用升华式升华方法和量化指数调制。把信号是mendekomposisi技巧之一sub-band一分为二,即sub-band低和高。QIM是一种计算或利用额外信息进行水位表计算的有效方法。水标记音频使用音频文件格式为*.wav 10秒,使用四种音乐类型,即流行、古典、摇滚和金属。黑白图像水印的插入和各自的* . bmp格式的大小32x32 64x64像素。测试是通过测量SNR、ODG、BER和PSNR的值来进行的。插入了水印,以耐久测试的音频提供7种攻击LPF、BPF HPF、MP3压缩,噪音和回声。这项研究有价值的最佳结果乔85.32分贝,ODG -8,34x10-11, BER 0, PSNR∞。关键词:水标记,QIM, LWT,压缩Sensing。ABSTRACTThis research developed Compressive Sensing (CS)为音频用Wavelet watermarking技巧用金币(把)和Quantization指数调制(QIM)方法。把一号技巧到decompose是信号进入2 sub-bands, namely sub-band低和高。QIM是个computationally efficient方法或watermarking calculation用资讯网措施。音频watermarking干得是用和* . wav格式音频文件持续10秒过去4 genres著作百科全书》的音乐,namely,经典流行、摇滚和金属。水印是inserted (in the form of black and white形象* . bmp格式每测量32x32和64x64的像素。《价值》做测试是由测量乔,ODG BER和PSNR。音频that had been inserted水印和赐予7是测试它的durability kinds of the attacks美国如此LPF BPF HPF, MP3压缩、噪音和回声。这个研究有论点与乔的最佳价值85。32分贝,ODG的公关之价值。34x10-11、个人价值的0和∞的PSNR价值。安装:watermarking音频,把QIM Compressive Sensing。
