Building a mashup that truly works requires two things above all else — a clean acapella and a perfectly matched instrumental layer. 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 OGG and receive six lossless separated components: vocals, piano, guitar, bass, drums, and other instruments, all delivered within seconds. The acapella 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 Cakewalk and use our BPM & Key Finder to match the tempo and key of both tracks before combining them. Amazing for DJs and audio engineers working in music production who are creating music education, DJ sets, or experimenting with creative remixing. 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.

"Jean Michel Jarre - Calypso Remastered" is one of those tracks where the vocal performance alone is worth isolating and studying in detail. Extracting the acapella gives sound designers and arrangers access to a industry-standard isolated vocal file that is perfect for a cappella arrangements and harmonies and TikTok and Instagram content creation. Import it directly into Reaper and start building something entirely new around the original performance. Unbeatable for game developers who want a clean vocal stem without any compromise. Harmonic mixing starts with knowing the key — our BPM & Key Finder detects both the musical key and tempo of any uploaded track, making it the perfect companion to our extractor. AI-powered stem separation continues to improve rapidly, with the latest models achieving quality that rivals what was previously only possible with access to original multitrack sessions.
