我正在创建一个基于节奏的音乐游戏，从理论上讲，您应该可以选择任何想要的歌曲。这是使用C＃在Unity（5.4.1）中创建的。
实时检测并通过可视化器将歌曲的音调显示给用户。
我遇到的问题是我创建了一个可视化器，但这几乎无法显示较高音高的音符。我担心这是因为（与大多数音乐一样）一次播放多个音高（出于测试目的，我在等待有声音的家伙给我音乐的同时使用了Darude Sandstorm）。最终，我希望这种音高检测可以告诉用户是击高，中还是低音。
我试过使用
GetComponent<FFT>().PitchValue;
和
AudioListener.GetSpectrumData(2048, 0, FFTWindow.Hamming);
我猜担心是无法同时播放多个音高的歌曲（即基本音调超过高音）。
我很想听听任何建议或知道是否有人克服了类似的问题。
这是我目前正在使用的示例，我已经尝试了许多不同的在线解决方案（某些信息实际上来自注释代码链接的教程），如果我继续阅读，我打算完全参考。这条路（我已经在兼职上工作了几个星期）。它看起来很漂亮，但我似乎无法充分利用它。在没有if else语句的情况下，它可以很好地用作可视化工具，这就是我目前正在尝试和尝试的地方。我正在追踪this tutorial

到目前为止，感谢您的评论，对不起，我一开始没有附上
最佳答案
万一有人在做类似的事情，我设法将音高分开，因为它们是使用数组访问FFT频谱数据的。
欢迎所有反馈。
我是通过学习FFT的工作原理（强烈推荐可汗学院）并找到这个很棒的家伙视频-https://www.youtube.com/watch?v=V_8JSWVT36k在JS中做同样的事情发现这一点的。
