Hazbin Hotel - You Didn't Know (Charlie & Emily Vocals Separated)

credits to u/LucidFir for teaching this:

The program is called Ultimate Vocal Remover 5 (PC Only).

First, press Select Input and select your song.
Next, make sure the "Choose Process Method" is set to MDX-Net
Then set the "Choose MDX-Net Model" to "Kim Vocal 2" (you'd have to download it within the app first.)
Make sure Instrumental Only is not ticked
Next press Start Processing
Once finished, find the output audio, and select that as in the input
This time, set the Process Method to VR Architecture
Then, set the "Choose VR Model" to "5_HP-Karaoke-UVR" (you'd have to download this first too.)
Make sure Vocals Only or Instrumental Only is not ticked
Then Start Processing
The Vocal Output will be the leading vocals
The Instrumental Output will be the backing vocals

I also put Emily's vocals through multiple random audio enhancer sites, and added a bit of reverb to both voices.
