Stemline101 lets you split any song into its individual parts — vocals, drums, bass, guitar, synth, and more — using AI-powered audio source separation. Once a track is split, you can remix it, blend stems from different songs together, and build entirely new mixes right in your browser.
What You Can Do
Upload and split — Drop in an MP3 or WAV and Stemline101 automatically separates it into up to six stems: vocals, drums, bass, guitar, synth, and other instrumentation.
Build a personal stem library — Save stems from every track you split so they're ready to load instantly, without re-processing.
Mix live — Load stems from multiple songs onto our built-in DJ-style mixing board. Adjust gain, EQ (highs, mids, lows), key, and tempo per channel, then blend them together in real time.
Key and tempo matching — Shift the pitch or tempo of any stem so tracks in different keys or BPMs can be mixed cleanly.
Download your stems — Export separated stems for use in your own DAW, video projects, or live sets.
Who It's For
Stemline101 is built for DJs, remixers, producers, and hobbyists who want more creative control over the music they work with. Whether you're isolating an a cappella for a mashup, pulling drum stems for a sample pack, or building a live mashup set that blends vocals from one track over the instrumental of another, Stemline101 gives you the tools to do it without expensive studio software.
How It Works

Automatic splitting — Our audio separation engine processes the track into clean stems.
