which features fundamental frequency is correlated? I'm unable to compute $f_0$ (fundamental frequency) in librosa feature extraction. By ready much in github issues check the second comment. I see that $f_0$ is correlated with some other features (like zero_crosssing) easy to extract from librosa.

What are these features except for that one I give? Is this correlation super high so that they can replace $f_0$?
