推荐答案

在一篇 StackOverflow 帖子中很难解释这一点.一般来说，最简单的节拍检测算法通过定位声能中的峰值来工作，这很容易检测.更复杂的方法使用梳状滤波器和其他统计/波形方法.有关包括代码示例在内的详细说明，请查看这篇 GameDev 文章 出.

This is challenging to explain in a single StackOverflow post. In general, the simplest beat-detection algorithms work by locating peaks in sound energy, which is easy to detect. More sophisticated methods use comb filters and other statistical/waveform methods. For a detailed explication including code samples, check this GameDev article out.
