AI Stem Splitter is an online tool that uses Meta AI's htdemucs model to separate any song into up to six clean stems (vocals, drums, bass, guitar, piano, other) for karaoke, remixing, and music production.
AI Stem Splitter is a web-based audio separation service powered by htdemucs, the hybrid transformer model from Meta AI that won the 2022 Sony Music Demixing Challenge. It takes any audio file (MP3, WAV, FLAC, M4A, AAC, OGG, WEBM) up to 50 MB and up to 20 minutes long, and outputs up to six isolated stems: vocals, drums, bass, guitar, piano, and other instruments. It also accepts YouTube or SoundCloud URLs for direct processing. The service is built by an independent team (not Meta) and offers both free and paid tiers.

Yes. Uploads are processed securely and not shared. The service does not store your files longer than needed for processing.
The service uses htdemucs, the same model that won the Sony Music Demixing Challenge. It produces cleaner separation than typical 4-stem models, with less bleed between vocals and drums/bass, as demonstrated in the spectrogram comparisons on the site.
