Go! Go! MANIAC - Bass Only (Highest Quality)【MIO】K-On!!

All canonically played by Mio Akiyama (秋山 澪) on Elizabass (エリザベス) in the full version of けいおん！！S2OP1!
It's a Christmas miracle! I use these for 3D music in VRC but I want to share them because the quality is so uniquely high!





No AI or other filters were used at all. It's isolated using only phase cancellation. This noise cancelling technique is applied in many layers to the special instrumental versions of this song taken from one of the official K-On CD releases. In each of those instrumental tracks a different instrument has been removed, kinda like instrumental karaokes. Basically what I did is I magically inverted everything across each other in a very specific way, so that the one instrument that's normally missing became the only one playing here! The bass might sound like it's volume peak clipping at parts so I checked again but my method for making this one isn't any different from the other tracks. Must be an artifact.

You might think that it's way easier to simply put the missing instrument track over the full instrumental track. While that's true, you can't get the same quality isolation this way - at least for this song - because of major rendering differences between these tracks. Look at the tutorial I made in the playlist description for more details:

I think the very quiet parts from the other instruments carrying over is mostly from the many small audio compression differences between the tracks, although I kinda like it like that. It feels like the sound is bleeding over from them wearing headphones, playing along to the song or something

Thanks for listening, use this as you wish!
