c# – 音乐的音高检测

实时地检测并通过可视化器向用户显示的歌曲的音高.

我遇到的问题是我创建了一个可视化工具,但这几乎没有显示更高音调的音符.我担心这是因为(和大多数音乐一样)一次播放一些音高(为了测试我在等待声音人给我音乐时使用Darude Sandstorm).最后,我希望这种音高检测能够告诉用户是高音,中音还是低音.

我试过用了
????GetComponent< FFT>()PitchValue.
和
???AudioListener.GetSpectrumData(2048,FFTWindow.Hamming);

我想恐惧的是,它不能在一次播放多个音高的歌曲上完成(即基础覆盖高音高).

我很乐意听到任何建议或知道是否有人克服了类似的问题.

这是我现在正在使用的一个例子,我已经尝试了许多不同的在线解决方案(其中一些信息实际上来自于评论代码中链接的教程),如果我继续,我打算完全参考这条道路(我已经在这段时间工作了几个星期).它是一个非常可视化的,但我似乎无法充分利用它.这可以作为没有if else语句的可视化工具,这正是我正在进行一些试验和错误的地方.我跟随this tutorial
