Solmi's AI stem splitter separates a finished song into individual stems — vocals, drums, bass, and instruments — in seconds. Upload a track and download each part for remixing, sampling, karaoke, or production. Sign in with a free account to split: 2 stems use 10 credits, 4 stems 15, and 6 stems 20, and free credits refill to 10 every day. Each stem exports as a standard audio file you can drop into any DAW.
A stem is one part of a song isolated from the rest: the vocal, the drums, the bass, or everything else. Studios keep stems from the original session, but for a released song all you have is the stereo mix. An AI stem splitter is trained on thousands of songs where the separate stems were known, so it learns what a voice, a kick, or a bass guitar looks like inside a mix and pulls each one out. The result is not the original session file, but on most modern productions it is clean enough to sample, remix, practice with, or mute for karaoke.
Remixes and flips: take the vocal and write a new beat under it. Sampling: lift a drum break or a bass line without the vocal bleeding through. Mashups: pair the acapella from one song with the instrumental of another, after matching tempo with the BPM finder and pitch with the pitch changer. Practice: mute your own instrument and play along with the rest of the band. Karaoke and covers: keep the instrumental and sing over it, or extract the vocal to study a phrasing. Sound design: reverse a stem or slow it down for textures the original never had.
They run on the same separation model and differ only in what you download. Use the vocal remover when you only want the instrumental. Use the acapella extractor when you only want the voice. Use the stem splitter when you want the drums and bass on their own tracks too, for remixing or for a full band practice mix.
| Tool | You get | Best for |
|---|---|---|
| Stem splitter | Vocals, drums, bass, other, each as a file | Remixes, sampling, band practice |
| Vocal remover | Instrumental only | Karaoke, covers, backing tracks |
| Acapella extractor | Vocal only | Mashups, vocal chops, studying a vocal |
| Instrumental maker | Instrumental, tuned for full songs | Backing tracks for live sets |
Separated stems are the raw material for a remix: turn a vocal or cymbal stem into a backwards riser with reverse audio, then write new words for the instrumental with the AI lyrics generator, or battle bars with the diss track generator. When the remix is done, make its artwork with the album cover maker.
A stem splitter uses AI to separate a finished song into its individual parts (stems) — typically vocals, drums, bass, and other instruments — so you can remix, sample, or rebalance a mix.
Solmi's AI stem splitter isolates vocals, drums, bass, and the remaining instruments from a single mixed track, giving you separate downloadable stems.
Yes, with a free account and no credit card. A 2-stem split uses 10 credits, 4 stems 15, and 6 stems 20, and free credits refill to 10 every day, so one 2-stem split a day is free.
Use the vocal stem for acapellas and remixes, the instrumental stems for karaoke or beat-making, and the drum or bass stems for sampling and production.
Upload MP3, WAV, M4A, AAC, OGG, or FLAC. Each separated stem exports as a standard audio file you can drop into any DAW.
