Audio-Watermarking-in-DCT
说明： 本文在DCT噪声信号模型研究的基础上,提出了一种新的音频水印嵌入位置选择策略和一个应用该策略的自适应音频水印算法. 通过定义DCT系数的噪声敏感度,建立了水印嵌入位置和嵌入水印后的音频信号的听觉感知性之间的关系,根据音频水印的不可听性的要求选择最优的嵌入位置,然后调节水印强度来满足鲁棒性的要求,从而最大程度地保持音频水
印的不可听性和鲁棒性,为解决音频水印嵌入过程中不可听性和鲁棒性之间的矛盾提供了一种策略.(Though m any w orks in the literature agree that w aterm ark should be em bedded in the middle2fre2

从物理的角度看，音乐是不同频率，不同时长声波的组合，声波的频率表示不同的音调，声波的时长反映不同的节奏，根据该原理，将不同频率，不同时长的声波进行有序组合，则能成为音乐，利用MATLAB对不同频路信号的组合及分析功能，能够进行简单的音乐合成。(From a physical point of view, the music is different frequencies, not at the same time the combination of the long acoustic wave, the frequency of the acoustic wave which means that a different tone, sound waves reflect the length of time the type of rhythm, based on the principle of different frequencies, not at the same time long waves are conducted orderly composition, to become the music, using MATLAB combination of signals of different frequencies Road and analysis capabilities, able to perform simple music synthesizer.)
