OK, so I've been playing with the new beta release just posted and I'm finding that the vocal removal isn't quite on par with the current Google Colab results. I tried all 3 models and it appears that for the song I already have done using the Google Colab method, I don't really hear any improvement differences. That's not saying it's useless. It's saying I will have to mess with another track to hear for sure that Google Colab can't currently do yet. It will probably have to be when the final release is finished.
