Eight AI tools that split a song into vocals, drums, bass and other stems, ranked: LALAL.AI, Moises, Ultimate Vocal Remover, MVSEP, Logic Pro, Ableton Live, iZotope RX 12 and Fadr, with prices, stem counts and output quality.
LALAL.AI is the best stem splitter for most people: its Andromeda model splits vocals, drums, bass, guitar and piano, exports lossless WAV or FLAC, and its Pro plan adds a plugin that separates seven stems offline inside your DAW.
Moises is the pick for musicians who practice along with songs, with up to 27 stem types, including separate drum-kit parts, and apps on phone and desktop.
Ultimate Vocal Remover is free and runs locally, and its beta build runs BS-RoFormer models, the family that tops MVSEP's public quality leaderboard.
If you already own Logic Pro or Ableton Live 12 Suite, stem separation is built in, with no extra cost.
Splitting a song for practice is fine, but releasing a remix needs permission for both the recording and the composition.
We looked at how cleanly each tool separates vocals and instruments, how many stem types it offers, output formats and quality, where it runs (browser, desktop, plugin or DAW), free limits and price.

LALAL.AI is a web-based stem splitter, and its Andromeda model, launched in December 2025, has added drums, bass, guitar and piano during 2026.
What works: Andromeda separates vocals, drums, bass, guitar and piano, and the full tool also splits synth, strings and wind, with separate tools for lead and backing vocals and for removing echo and reverb. It takes MP3, WAV, FLAC, AIFF and video files and exports MP3, WAV or FLAC, up to 20 files at a time. Lite costs $7.50 a month billed yearly ($90) with 90 fast minutes, and Pro ($15 a month billed yearly, or $19.99 monthly) adds 250 fast minutes, the API and a VST plugin that separates seven stems offline on your own computer.
What doesn't: The free plan gives 10 minutes on a slow queue and lets you preview results but not download them, and unused fast minutes don't roll over. The plugin's Audio Unit version is still in beta.
Best for: Producers and creators who want clean stems and a plugin, without setting anything up.
Moises is a stem splitter and practice app for phone, tablet and desktop.
What works: Paid plans separate lead and backing vocals, guitars, bass, piano, keys, strings, winds and drums, and the top Pro plan adds brass, percussion and separate kick, snare, toms, hi-hat and cymbals, for 27 stem types in all. It also changes key and tempo for practice. Moises Live, a free desktop app, turns down any instrument in whatever audio is playing on your computer, in real time and on-device.
What doesn't: The free plan allows five uploads a month, songs up to five minutes, and only a two- or four-stem split. Moises Live adjusts volume only and can't export stems, and Moises shows plan prices only after you sign in.
Best for: Guitarists, bassists, drummers and singers who play along with songs.
Ultimate Vocal Remover (UVR5) is a free, open-source desktop app, with installers for Windows and Mac, that runs separation models on your own computer.
What works: It runs many separation models, including Demucs and, in its beta build, BS-RoFormer and MelBand RoFormer models. BS-RoFormer is the model family at the top of MVSEP's public quality leaderboard. Nothing leaves your machine, there are no minute limits, and you can chain models for cleaner results.
What doesn't: The last stable release is from 2023, so the best models need the beta build from its GitHub releases page, then a download from its in-app Download Center. There's no Linux installer, and choosing between dozens of models takes some reading.
Best for: Tinkerers who want top-quality stems for free and don't mind setup.
MVSEP is a web separator that also runs a widely used public quality leaderboard for stem separation.
What works: Its own BS-RoFormer model tops its multisong leaderboard for vocals, at 12.33 dB SDR, a standard measure of separation quality where higher is better. Free users can separate files up to 10 minutes, 50 times a day, with WAV or FLAC for registered users. Premium credit packs start at $3 and add ensemble models, 32-bit WAV and full API access.
What doesn't: The interface is built for enthusiasts, with long lists of models, and free jobs can wait in a queue.
Best for: People who want the highest-scoring separation without installing anything.
Logic Pro's Stem Splitter separates a song into vocals, drums, bass, guitar, piano and other, right in your project.
What works: It runs on your Mac with no upload, and guitar and piano stems arrived in 2025. Logic Pro costs $199.99 once on the Mac App Store, or comes in Apple Creator Studio for $12.99 a month, and runs on iPad too.
What doesn't: It needs an Apple silicon Mac, and there's no Windows version. It offers fewer stem types than LALAL.AI or Moises.
Best for: Mac producers who want stems without leaving their DAW.
Ableton added stem separation to Live 12 Suite in version 12.3, in November 2025, using technology from Music.AI, the company behind Moises.
What works: It splits audio into vocals, drums, bass and others on your own computer, with High Speed and High Quality modes. It also runs on Push 3 Standalone. Version 12.4 lets you separate just a time selection and merge chosen stems back into one track, and exported stems keep the source's bit depth.
What doesn't: It's only in the Suite edition, which costs far more than a stem tool on its own, and it offers four stems.
Best for: Ableton producers who sample and remix inside Live.
RX is the standard audio repair suite, and RX 12 improved Music Rebalance, its stem separation tool.
What works: Music Rebalance raises or lowers vocals, bass and percussion in a mix, and RX 12 adds a real-time Music Rebalance plugin and a Stems View for working with separated parts. RX 12 Standard costs $399, and Scene Rebalance, which splits film and TV audio into dialogue, music and effects, is in RX 12 Advanced ($1,399).
What doesn't: It's expensive if all you need is stems, and it's built for repair and mixing rather than quick vocal removal.
Best for: Audio engineers and post-production editors.
Fadr is a browser-based stem splitter and remix tool.
What works: The free plan splits vocals, melody, drums and bass, downloads MP3s and detects MIDI, key and tempo, so you can pull a melody into your DAW. Plus costs $10 a month, or $100 a year, for 18 stem types, its Pro Stems model and 32-bit WAV downloads.
What doesn't: Free downloads are MP3 only, and its remix tools are basic next to a full DAW.
Best for: Beginners and bedroom producers who want stems and MIDI for free.
DJ software now separates stems live, so you don't need to prepare them in advance. Serato DJ Pro splits vocals, melody, bass and drums in real time, rekordbox 7 has a four-stem mode, and djay Pro's Neural Mix offers two, three or four stems. These are built for live mixing rather than exporting files.
For practice, study and private use, splitting a song is common and every tool here allows it. Releasing a remix, cover or sample is different: you need permission from whoever owns the recording and whoever owns the composition, whether you charge for it or not. Some labels license official stems for remixes, which is the safer route.
LALAL.AI, for most people. Its Andromeda model removes vocals cleanly, exports lossless WAV or FLAC and starts at $7.50 a month billed yearly, with a free plan for previews. Ultimate Vocal Remover is the best free option if you're happy to run it on your own computer.
Ultimate Vocal Remover, which runs RoFormer models locally for free. MVSEP and Fadr are free in the browser, and Logic Pro and Ableton Live 12 Suite include separation if you already own them.
Most tools split vocals, drums, bass and other. Paid tools go further: LALAL.AI adds guitar, piano, synth, strings and wind, and Moises offers 27 stem types, including individual drum-kit parts.
On MVSEP's public leaderboard, MVSEP's own BS-RoFormer models score highest, and Ultimate Vocal Remover's beta build runs models from the same family. Commercial tools like LALAL.AI and Moises don't publish comparable scores.
Only with permission. Using stems from someone else's song in a release needs a license for both the recording and the composition.
