Our free online stem separator is trusted by audio engineers, hobbyist musicians, and artists around the world because it delivers consistent, lossless results on every single track, regardless of genre or recording style. Upload any audio file in MP3 format and our AI will isolate six individual multitrack stems — vocals, piano, guitar, bass, drums, and other instruments — within seconds, with no loss of audio quality and no artefacts. The isolated vocal track gives you a clean acapella perfect for music portfolio building. The background music is ideal for vocal practice. The individual instrument stems open up extensive creative possibilities for Ableton Live sessions in LMMS. Amazing for anyone working in music production who wants professional audio separation without any of the complexity or cost of traditional studio methods. Use our BPM & Key Finder tool alongside the stem separator to get the full picture — exact tempo, musical key, and clean individual stems all in one place. Music bloggers and critics sometimes use extracted stems to analyse specific production choices in detail — isolating a particular instrument to discuss its role in the overall arrangement.
