Topic: Filter Folder for (not) analyzed STEM files
DJ HeyePRO InfinityMember since 2017
Dear Support,

I would like to make a filter folder that shows me all files who need tobe analyzed for STEMS.
(Like the filter option: isscanned=0)

Is that possible?

This is not currently possible.

Precomputing stems is only advised when your system is not able to compute quickly enough on-the-fly.
Also worth noting that if you precompute every file, you will need a lot of storage capacity to do so. The stems file is 2-3x larger than the original file and you must keep the original file too.

Thanks for the reply, i didn't know STEM needed that much permanent space per (mp3) file.
If you have thousends of music files, you could run out of disk space.

I'm running VDJ on a Intel NUC with an i7 (7567U with no GPU).
An 3:35 min MP3 takes about 10 secs to analyze.

Which is a quite acceptable time IMHO. So you should not pre-compute stems...

This is what I did on my side to achieve this need (filtering on files from my iTunes/Music app folder only):
Precomputed Stems = 0 and File Path contains /users/nicolas/Music/MusicLibrary/

My next step is to find a way to filter tracks based on the stems:
- smart folder containing big vocal tracks
- smart folder containing instrumental-only tracks, ...

Is this a feature now? I think I may have to precompute for stems 2.0.
