Building a mashup that truly works requires two things above all else — a clean vocal melody and a perfectly matched music arrangement. Our free AI stem separator provides both, along with four additional isolated instrument stems that give you even more creative flexibility. Upload any track in MP3 and receive six crystal clear separated components: vocals, piano, guitar, bass, drums, and other instruments, all delivered within seconds. The vocal melody gives you the clean acapella your mashup needs, while individual instrument stems from a second track can provide a richer, more layered backing than a simple instrumental alone. Import everything into Audacity and use our BPM & Key Finder to match the tempo and key of both tracks before combining them. Highly effective for sound designers and music teachers working in music production who are creating professional mixing, school projects, or experimenting with music theory study. Knowing the BPM and musical key of a track before working with its stems is what separates a professional-sounding remix from an amateur attempt — use our free BPM & Key Finder to get both instantly.
