Okay, this is way inside baseball, but I fiigure if there are any people on Earth who knows the answer to my question, this is the likeliest place to find them lurking.
A couple of months ago, I installed Spleeter at home with a Windows GUI. This is a freeware that does a remarkable job of separating vocal tracks from instrumental in existing recordings (it also does a remarkable job of further separating stems, but the short first description is how I’m using it).
So I’ve been popping AIFFs of pop recordings into it and getting out, basically, “instrumental versions” and “vocal-only versions” of the recordings. It’s mostly a novelty, but I’ve found that I like playing the instrumentals of recordings I know well.
So after the conversion, I have three sets of files - the uncompressed AIFF of the CD in my attic, the .WAV of the instrumental and the .WAV of the vocals. I edit the tags sensibly on the .WAVs (so all three sets list Stevie Wonder as the artist, but the AIFF is still identified as Innervisions, and the other two as Innvervisions - vocals and Innervisions - accompaniment.
The short version, though, is that that isn’t getting me anywhere. I often get one or the other of the “new” directories to show up, but usually it’s just perplexing. They don’t show up as versions of each other; often, Roon identifies one as the original item, and usually the other doesn’t appear at all.
I’m not upset, because I know this is kind of a perverse use case for a software that’s trying to match up against a directory based on file size & title.
The “new” files aren’t listed under the main artist/album directory structure, because I want to keep them all in the same place on my hard drive.
They are .wav files, and I’m wondering if that’s part of the tag / ID problem - I think I knew that .wav tags aren’t written in the file itself. Maybe I want to look into file conversion?
Any input welcome.
