Choral part track mixer? Eventually? 🤷

Converting part tracks to stems

The JS file tracksToStems.mjs takes all the files in tracks/raw and does the following:

• Determines song title from file names and groups files by song
• Creates a directory for each song in the tracks directory
• For each song:
  • Run the demo/balanced track through spleeter to isolate the accompaniment
  • If the predominant part is panned L, create files isolating the left channel
  • If the predominant part is mixed louder, do something Jacob hasn't thought of yet
• Generates a manifest file describing the generated files

node tracksToStems.mjs

For copyright reasons, the entire tracks directory is gitignore'd.

I didn't account for Windows-style paths, so idk if this'll run on Windows. Sorry not sorry.

Spleeter is a dependency of this script. The first time you run the script, spleeter will take some time to download its pre-trained models so be aware that it'll take a hot sec.
