Possible to add multiband?

Hi, thx for your great work!
I wonder is it possible to add multi band to further improve inference speed like https://github.com/MasayaKawamura/MB-iSTFT-VITS

Thanks for your suggestion. This looks interesting and worth trying. I think it can definitely do it and make it having comparable performance while being two times faster. I’ll try when I have time but I’ll leave this issue open if anyone else would like to try.
