Story time!

I was with some friends, one a CS student and the other one's a mechanical engineer student with coding like a hobby.

I was listening to a song from which the band released the stems (individual tracks) of a song, and this dude made an anime version of it.

Me: Oh God, this is awesome
Mech: how did he do that?
Me: What? The song?
Mech: Yeah, how did he split the voice and everything, is the music like an Ajax request and he queried for the voice

Me and my other friend lock eyes and began to laugh so fucking hard.

Me: that's not how it works, why did you though that?
Mech: I don't know
