pitch - 钢琴音高检测

Question

我阅读了很多关于 FFT 和音高检测算法（自相关、重叠窗口、HPS ......）的文章和讨论。当我们弹钢琴时，不仅有一个频率，而且有很多 - 高频和低频，那么钢琴最好的方法是什么？

I dont know much about what you are trying to do, but it seems to me you need to run some high pass and low pass filters, isolate your data set so you can get the pitch from the noise. Piano has many frequencies to give you the tonal characteristics of its sound, but if you only care about pitch, (the exact note being hit) then the rest of the waveform is noise to you. Hope this helps.
