how to reproduce the pitch, intonation and other nuances of a voice? I would like to find a tutorial or a guide (Intonation and Pitch in RVC or mastery of RVC Configuration)?

[GPU-server]

I know how to reproduce a voice using a certain number of data, clean them and then run RVC. But I know nothing about the index file, or anythign related to: n_fft, hop_length, win_length, and n_mels, IVF, Flat ??

I would like to learn to not only reproduce a voice (vocal timbre) of someone, but also how to reproduce the pitch, intonation and other nuances of a voice.

Is that possible with RVC?
If so, where can I learn that please?
