frequently asked questions
Stem Lab is a browser-based stem splitter for music source separation. It separates a finished stereo song into four workable stems: vocals, drums, bass and the remaining instrumentation. This gives you individual musical parts for vocal isolation, drum separation, bass isolation, instrumental creation, remixing and rebuilding the balance of a finished mix.
Stem Lab is designed around local, on-device audio processing wherever technically practical. The goal is private browser-based stem separation, so your music can be processed locally by your own device instead of being uploaded to a remote audio-processing service by default.
Yes. After stem separation, you can preview vocals, drums, bass and the remaining instrumentation individually, listen to different combinations, rebuild the mix and download the stems or mix you want. Stem Lab is built for practical stem mixing and recombination, not just one-click vocal removal.
Yes. You can leave the vocal stem out and work with drums, bass and the remaining instrumentation to create an instrumental or backing mix. You can also isolate individual parts, change which stems are present and rebuild combinations for remixing, practice, production or further audio processing.
Stem separation is the beginning of the DivineWorx workflow. Once you have separated vocals, drums, bass and instruments, you can rebuild the balance you want and take the material forward into Audio Lab for audio restoration, EQ, frequency balancing, tone shaping, stereo imaging, dynamics processing, song enhancement and mastering.
Stem Lab is designed for musicians, producers, remixers, independent artists and creators who want browser-based stem separation without being locked into a finished song. It can support remix workflows, vocal isolation, instrumental creation, backing tracks, stem balancing and preparation for mastering inside the wider DivineWorx creative pipeline.
