Native Instruments has released Stem Creator, a free application for creating STEMS formatted audio files, as a beta download.
STEMS is an open file format that lets you distribute tracks that incorporate a full mix, plus four stem tracks – such as drums, bass, keys and vocals. Each of the four stem tracks can be individually mixed, allowing for more performance options and making it easier to create new mixes, mashups, instrumentals, a cappellas and more.
Here’s the official video intro:
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 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:
A standard master version of the track is included in the file and can be played in stereo with any compatible audio player following standard mp4 specs, like iTunes for example. To play with a track’s individual stems, Stem-compatible software or hardware is required.
For more information about the new format, see the STEMS site.
