Building a stem based hifi system
I want to listen to any music (probably mostly recorded in stereo), run it through a "stem based" splitter - I believe most audio software comes with AI modules to be able to split into e.g. a 4 channels stem stream that's instrument specific per channel. Output into 4 speakers in a row (1 left, 1 middle/left, 1 middle right, 1 right, each spaced apart from each other). The goal is to create the sound image of sitting in front of a band, e.g. vocals on the middle/right speaker, drums on left speaker, bass on right speaker, guitar on middle/left speaker. I'm sure y'all have used software like Reaper or Pure Data to do this before - can you point me in the right direction?
Overall I want the sound to be more immersive, almost like a live event at home but avoiding a complex speaker setup needed for Spatial Audio.
