[Discussion] Does Spleeter tech powers Apple Music Sing?

Can we confirm yet if Apple Music's newest exciting Karaoke feature called "Apple Music Sing" is **_powered by Spleeter's tech?_**


> Ever since the launch of the [Live Lyrics feature](https://youtu.be/Y7zfExL8Yes) back in 2019, I knew damn well Apple Music just created the best Karaoke UI implementation yet.

Anyone testing out Beta versions of tvOS, iOS or iPadOS, can we investigate and confirm this?

Because I really wanted to open up a discussion, if it is really justified for Apple to bar this amazing party feature to their newest [Apple TV 4K box only.](https://9to5mac.com/2022/12/08/apple-music-sing-karaoke-compatible-devices/)

I've run your tech on my M1 Macbook Air and I'd say it's not that too hardware demanding.
So I really wanna understand, if it is really that hardware demanding to run this in _real time music?_
