Best AI Stem Splitters in 2026 (Tested by a Mixing Engineer)

Disclosure: I build StemConsole, one of the tools below. I have placed it where it belongs, which is not first for every job. Details read from each vendor’s own pages in September 2026. Plans change, so confirm current terms before you pay.

How I compared them: what to listen for

I have spent 20 years mixing and mastering records, and I use separation constantly: for remix prep, for pulling a reference apart, and for teaching students to hear what the bass player is actually doing. Feature lists only get you so far. These are the four problems that separate a usable split from a frustrating one, and the ones to check with any tool.

1. Vocal bleed in the instrumental. Solo the instrumental and listen through the chorus. Weak separation leaves a ghostly, phasey vocal behind, especially on sustained notes and stacked harmonies. This is the single most common failure for karaoke and backing tracks.
2. Hi-hat and cymbal smearing. Solo the drums. Hats should stay crisp and defined. Poor models turn them into a watery, swishy wash, or pull some of them into the other stem.
3. Bass and kick separation. Solo the bass. You should hear notes, not a thump on every beat. Kick drum leaking into the bass stem (and bass leaking into drums) is where models differ most on modern, low-heavy productions.
4. Reverb tails. Listen to the vocal stem at the end of phrases. Good separation keeps the natural tail attached to the voice. Weaker results chop the tail off, or leave it floating in the instrumental where it sounds like a ghost.

Use the same dense, busy song for every tool, and listen on headphones. A sparse acoustic track makes every splitter sound great. Results also vary by song more than by brand among the strongest tools, which is why the right choice usually comes down to workflow, platform and price.

The tools, one by one

1. StemConsole: best free browser splitter with a live mixer

StemConsole is the tool I built, so here is where it fits. It splits in the browser and opens the result straight into a live mixer: every stem gets a channel with solo, mute and level, so you audition and balance before you download anything, then bounce the exact mix. Your first split needs no account.

Free: Vocal Remover (vocals and instrumental) and Quick Split into 4 stems (vocals, drums, bass, other). A free account gets 5 splits a month, up to 2 of them 4-stem, with MP3 downloads and mix bounces, basic looping, saved sessions in My songs and share links. No watermarks, nothing to install, and it works on a phone.

Pro, $6.99 a month or $49 a year: Full Separation into 6 stems (adds guitar and piano), WAV, 100 splits a month, priority processing, and the practice room: speed change without pitch change, key change without speed change, named loops, count-in and tap tempo. Eligible users get a 7-day free trial. A $1.99 credit unlocks one 6-stem Full Separation with no subscription and never expires.

Where others win: no YouTube link import, no chord, BPM or key detection, no desktop app and no consumer API. Uploads are MP3, WAV, FLAC, OGG, M4A, AAC or WMA up to 200 MB.

2. Ultimate Vocal Remover: best free desktop and open source

UVR is free, MIT-licensed software for Windows, macOS and Linux that runs a library of separation models on your own machine, including Demucs 4-stem models and MDX-Net and MDX23C vocal models. There are no upload caps. You can also combine models in an ensemble for the last few percent of quality. The trade-off is setup and hardware: you install it, choose models and wait for renders. The project lists an Nvidia GTX 1060 6GB as the minimum for GPU conversions and recommends 8GB or more of VRAM; on a CPU it works, just slowly.

3. MVSEP: best for maximum quality control online

MVSEP is a web service exposing more than 100 separation models, so you can run one song through several and keep the best result. Free use allows 50 separations a day on files up to 10 minutes and 100 MB, with a low-priority queue and a captcha. Premium is credit based rather than a subscription and raises limits to 100-minute files, unlimited daily separations, WAV 32-bit float or FLAC 24-bit output, batch processing, API access and ensembles. The interface is plain and assumes you know which model you want.

4. Moises: best app ecosystem

Moises runs on the web, desktop, iPhone, iPad and Android, and adds chord detection, lyric transcription and a speed changer on top of separation, which makes it the most complete phone-first practice app. The free plan allows 5 uploads a month on files up to 5 minutes, split into 2 or 4 stems. Paid plans unlock up to 27 stem types and more uploads; Moises shows its prices after login and they vary by region. For the detailed comparison, see StemConsole vs Moises.

5. LALAL.AI: best pay-per-minute

LALAL.AI covers a wide range of stem types, including guitar, synth, and strings and wind, across web, desktop (Windows, macOS, Linux), iOS and Android apps. The free Starter plan includes 10 minutes. Lite is $7.50 a month ($90 a year) with 90 fast-queue minutes; Pro is $15 a month ($180 a year) with 250 fast-queue minutes, a VST plugin and API access. If you would rather buy time than subscribe, packs start at 750 minutes for $50. See StemConsole vs LALAL.AI or the best LALAL.AI alternatives.

6. Logic Pro Stem Splitter: best built into a DAW on Mac

If you already work in Logic Pro, start here. Stem Splitter sits under the Processing menu on an audio region and extracts vocals, drums, bass, guitar, piano and other parts, with presets for common combinations like acapella or instrumental. Apple added guitar and piano stems in Logic Pro 11.2 for Mac and 2.2 for iPad. It requires a Mac or iPad with an M1 chip or later. Logic Pro for Mac is $199.99 for new users; Logic Pro for iPad is $4.99 a month or $49 a year.

7. Ableton Live 12 Suite: best built into a DAW for Ableton users

From Live 12.3, Live 12 Suite can split any audio clip into vocals, drums, bass and others, with a High Speed mode and a High Quality mode. Processing runs locally with no internet connection, and Ableton notes it is slower on Intel Macs and older Windows machines because only the CPU is used there. It is not in Live Intro or Standard. Live 12 Suite is $749. There is no guitar or piano stem, so for guitar parts you will want another tool.

8. Fadr: best free option for producers and DJs

Fadr’s free Basic plan splits into vocals, melodies, drums and bass with MP3 downloads and MIDI detection, on uploads up to 10 minutes. Fadr Plus, at $10 a month or $100 a year, adds 18 stem types including kick and snare, 32-bit WAV, hour-long uploads and a Stems Plugin for your DAW. It leans towards remixing and DJ use rather than instrument practice.

9. BandLab Splitter: best free splitter inside a free DAW

BandLab Splitter is free with a BandLab account on web and mobile and splits into 2 stems (vocals and others) or 4 stems (vocals, drums, bass, other). BandLab Membership raises that to 7 stems, adding guitar, strings and piano, and converts stems to MIDI. It suits people already making music in BandLab’s online studio. BandLab notes Android may lag behind on the newest Splitter features.

10. Gaudio Studio: simple web splitting, bought by the minute

Gaudio Studio offers a Vocal Remover (Standard and High quality) and a multi-stem Instrument Splitter in the browser. The free trial is a one-off 10 minutes with MP3 output. After that you buy minute packs: $7 for 50 minutes, $16 for 200 or $79 for 1,200, which add WAV downloads, fast-track processing, storage and share links. Its Vocal Remover caps files at 10 minutes even on paid plans.

11. StemSplit: pay-as-you-go with link import

StemSplit offers 2, 4 or 6 stem modes, the 6-stem mode adding piano and guitar. You get 5 minutes free on signup, then packs from $2 for 10 minutes up to $30 for 300 minutes, with credits that do not expire and API access included. It can process a pasted YouTube or SoundCloud URL, and uploads are capped at 100 MB. See StemConsole vs StemSplit.
