Building a mashup that truly works requires two things above all else — a clean clean vocals and a perfectly matched music bed. 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 M4A and receive six pristine separated components: vocals, piano, guitar, bass, drums, and other instruments, all delivered within seconds. The clean vocals 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 Reaper and use our BPM & Key Finder to match the tempo and key of both tracks before combining them. The go-to solution for drama teachers and music enthusiasts working in music production who are creating loop creation, music therapy sessions, or experimenting with beat making. Our BPM & Key Finder tool analyses any uploaded audio file and returns the exact tempo in BPM and the musical key including major and minor scales — use it before working with your extracted stems.

The acapella from "Jay Z - Family Feud Feat Beyonc" is particularly prized by game developers working on acapella group rehearsals, who need a clean lossless vocal that they can layer, pitch, chop, or process without any backing music interfering with the result. music enthusiasts use it for vocal processing and pitch correction practice, while singers and vocal coaches rely on the isolation for detailed technique study. Available instantly through our free extractor and ready to use in Pro Tools. Unbeatable for backing vocalists who take vocal quality seriously in their creative work. Combining our stem separator with our BPM & Key Finder gives you everything you need for professional music production — clean isolated audio and precise harmonic and rhythmic information. The rise of bedroom production has made tools like our free stem separator more important than ever before — professional audio separation now available without professional costs.
