I was very dissatisfied when I realized that the MediaLibrary's GetVisualizationData() returns a bunch of zeros on WP7. What are the other approaches I could apply in order to compute and extract sound spectrum data from my MediaLibrary's song collection ?

P.S。它是书面的方式表明我工作的一个项目XNA。我会很高兴接受甚至Silverlight的相关办法，因为这是比较我与挣扎的一个普遍问题的

P.S. The way it's written suggests that I'm working on an XNA project. I would be glad to accept even Silverlight-related approaches, as this is more of a general problem I'm struggling with

推荐答案

您必须写自己的算法。这不太容易，但你要找的是什么（此页有一些链接让你开始）。

You'll have to write your own algorithm. It's not exactly easy, but what you're looking for is Beat Detection (this page has some links to get you started).
