在 C# 中从和弦中提取音符
目前我没有代码可以帮助我，但快速傅立叶变换可能与我的目标有关。
我想接受麦克风输入并从和弦中“提取”音符，无论它们是口语元音还是器乐音符。我想在某个提示后在列表中显示提取的频率值。提示并不重要。
感谢您的帮助，如果需要我会添加更多
At the moment I have no code to help me, but the Fast Fourier Transform probably has something to do with my goal.
I would like to take microphone input and 'extract' the notes from the chords, whether they are spoken vowels or instrumental. I want to display the values of the extracted frequencies in a list after a certain cue. The cue is not important.
Thanks for any help, I'll add more if needed

这已经在 SO 上讨论过很多次了，但本质上你是这样做的：
sqrt(re*re+im*im)）获取功率谱This has been covered many times on SO already, but essentially you do this:
sqrt(re*re+im*im)) to get power spectrum正如其他人已经提到的那样，对于详细解决这个问题存在很大的问题。但应该注意的是，在大多数这些问题中，您会发现提取构成和弦的音符非常困难，而且不准确。您可能最多只能做出有根据的猜测。
As others already mentioned there are great questions on SO addressing this in great detail. It should be noted however, that in most of those questions you will read that it is very difficult to extract the notes that make up a chord and will not be exact. You will probably have to end up making an educated guess at best.
