- 采用滤波器组,将盲分离与声源定位结合在一起。滤波器组中分别进行子带处理,并且在每个子带中进行声源定位,最后综合所有子带估计的方向得到多个声源的方位信息,同时将声源信息作为ICA分析的约束条件,可以在色噪声及多得到更好的盲分离效果。其优势在于用滤波器组进行多次的估计声源方向,再加以合适的权值均衡后即可得到更优的估计。-The use of filters will be blind source separation and sound localization together. Filter

- BestPractice is a tool to slow down or speed up music, either from a wave file, an MP3 file or directly from a CD. The thing is, that ordinarily the sound is distorted when slowed down our sped up - you get the effect like when playing a 45 rpm recor

- 我国目前对噪音污染的治理方法主要有两种:一种是将水泥路 面的改柏油路面第二种是在距离住宅窗户较近的道路两侧安装隔音 屏障。但效果均不理想。路面改变只可降低汽车行驶摩擦声的3~5 分贝左右。至于安装隔音屏障.由于声波的衍射特性,声音的传播可 以跨越隔音屏障,在中频,高频声波传播中,遇到难以穿透的障碍物 时,背面就有一个声波微弱的影区。所以此举只对相近楼层有所缓 解,对更高楼层的住户而言,效果并不明显-Our current treatment methods for noi

- 1)编程思路:首先,本练习因为要制作模拟钢琴的实例,所以首先要生成程序界面:先通过语句Image m_ImgUp生成键盘、鼠标松开时显示的键盘图片,再通过语句Image m_ImgDown生成键盘、鼠标按下时显示的键盘图片,最后通过语句m_ImgUp=getImage(getDocumentBase(),"img/up.gif")和语句m_ImgDown=getImage(getDocumentBase(),"img/down.gif")加载图片,生成钢琴界面。然后,因为要实现模拟钢琴效果,所以
