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，但你要找的是什么节拍检测（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).

下面是一些的Java源 - code 从 Mimim 库拍子检测。
