摘要
将伴随于迭代函数系统的码空间编码方法应用于音频的编码,然后通过在两个不同码空间的变换对音频进行置乱.实验表明该方法置乱效果好,一次变换后就能达到很好的置乱效果.
A method associated with iterated function systems＇ code spaces is applied to audio scrambling. Each sample point＇s position of audio signal is changed by a transformation between two different code spaces. Experimental result shows that this scheme is efficient for audio scrambling. It is characterized by the satisfactory scrambling result just after one transformation.
