Native Instruments has released Stem Creator, previously available as a beta release, as a free download for Mac & Windows.
Stem files use the .mp4 container format to store the four individual stems of a track within a single file. Using the file extension .stem.mp4, this single file can be managed just like an mp3 file.
Here’s a video intro to the format:
Here’s the Stem Creator demo video:
You can create a STEMS format file in three steps:
- Save four musical elements of a track as separate audio files;
- Import them into the Stem Creator Tool;
- Adjust the compression and export.
This creates a stem.mp4 file, ready for creative mixing with compatible software or hardware.
Stem Creator is a free download from NI’s Stems site.
