AI stem separation tools pull a finished recording apart into vocals, drums, bass and other parts for remixing, practice, sampling or film dialogue work.
This guide ranks products with readable prices and a stated vendor first, then weighs stem types, local processing, usage units and exit from archived or thinly described tools.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
In short
What AI stem separation tools software does
An AI stem separation tool analyses a mixed audio file and returns separate tracks for vocals and instruments, as downloads, plugins or an API for editors.
Every AI stem separation tool was judged on five points in a fixed order: setup effort, cost in practice, how data is exported, how easily you can leave, and the buyer it was designed for. A separate rule reserves the first three places for challengers and moves the household names to place 4 and below. Why those five, and why there is no score out of ten, is on the how we work page.
Minute-billed stem splitting with desktop app, VST plugins and API
Ranked #1 of 12 in Best AI Stem Separation Tools in 2026.
Published pricingEurope
A Swiss operator, OmniSale GmbH in Risch-Rotkreuz, publishes everything on one page. The always-free Starter plan allows 10 relaxed-queue minutes and 200MB uploads, while Lite and Pro are billed in euros and fast-queue top-ups in dollars.
A local desktop app and VST plugins make it a workbench rather than a web toy, but the page names no parent company and metering punishes multi-stem jobs.
What stands out
Minute-based billing
Local desktop app
VST plugins
Where it costs you
The VST plugin and API are reserved for Pro, so cheaper plans stay inside the apps
Every extra stem type you pick shortens the minutes a plan appears to hold
Right for
Producers who split many tracks and want a desktop app plus plugins
Wrong for
Buyers looking for one flat fee with no usage metering
SwitzerlandAlways-free Starter plan, then monthly or annual Lite and Pro plans in euros, plus one-time fast-queue top-ups in dollars; all prices published
Browser stem splitter with MIDI detection and a built-in remix maker
Ranked #2 of 12 in Best AI Stem Separation Tools in 2026.
Free tierPublished pricingElsewhere
Fadr bundles separation with MIDI detection and a remix maker, which makes it more of a creative toy than a pure splitter. Basic covers the four main stems at no charge.
Plus is the upgrade path: ten minutes becomes an hour of upload length, instrument stems appear, WAV is unlocked and API access arrives. Publicly stated limits are thin on Basic, so heavy users should test it before relying on it.
What stands out
MIDI detection
Remix Maker
WAV on Plus
Where it costs you
The free plan delivers MP3 files only, so lossless WAV needs the Plus subscription.
Individual instrument stems such as guitar, piano and strings sit in Plus rather than Basic.
The vendor states no country and credits Pebble without saying who owns Fadr.
Right for
Hobbyists who want a free first pass, MIDI output and remixing in one place
Wrong for
Engineers who must have lossless files without any paid step
Not stated by the vendorFree Basic plan with no numeric caps listed; Plus billed monthly or yearly at published dollar prices; no Plus trial mentioned
Type a song title and receive four stems on your own computer
Ranked #3 of 12 in Best AI Stem Separation Tools in 2026.
Published pricingElsewhere
This is the lowest-friction option on the list: install the app, type what you want, wait for four stems. Because it runs on your computer, quality and speed follow your hardware, and the Windows build targets CUDA graphics cards.
It does one job and lists nothing about batch work, limits or commercial terms, so professional users will want a vendor that states more.
What stands out
Desktop app
Four stems
Donation-funded
Where it costs you
It outputs four stems only, so guitar or piano cannot be pulled out separately.
The page names no licence for the code, so reuse terms cannot be confirmed from it.
Support is a Discord channel, and no company or country is stated.
Right for
Casual users who want a no-cost local splitter that starts from a song name
Wrong for
Teams needing a contract, a service level or a documented API
Not stated by the vendorDescribed by the vendor as totally free, with donations accepted; no paid plans, prices or trial listed
Audio editor that splits stems and lets you edit notes like MIDI
Ranked #4 of 12 in Best AI Stem Separation Tools in 2026.
Published pricingElsewhere
RipX goes past separation: stems are broken into notes that can be moved, deleted or replaced, with Sound Replacement and Edit Notes In The Mix named as features.
That suits remixers and arrangers who intend to rebuild parts. The cost is commitment, since you are buying a workstation rather than a splitter, and the site leaves the billing basis and the country unstated.
What stands out
Note-level editing
Sound Replacement
6+ stem output
Where it costs you
Whether the entry price is a one-off purchase or a subscription is left open.
Only RipX DAW PRO has a stated trial, and no permanent free plan is described.
It is a full editing environment, which is more software than someone wanting plain stem files needs.
Right for
Producers who want to rework individual notes inside separated stems
Wrong for
Anyone wanting a quick stem download without learning an editor first
Not stated by the vendorPaid from a published entry price with the billing basis not stated; 21-day trial of the PRO edition
Splits songs into up to eight stems with lyrics, chords and tempo
Ranked #5 of 12 in Best AI Stem Separation Tools in 2026.
Pricing on requestElsewhere
The product leans towards practice and DJ use: a browser mixer, editable timed lyrics, chord display and stem files that open in DJ software.
Analysis happens on the full song in one pass, which the vendor says yields up to eight usable stems. Prices were not visible where we looked, so the main work for a buyer is checking the plans page before committing.
What stands out
Up to 8 stems
Chords and lyrics
Stem MP4 export
Where it costs you
Uploads are limited to 100 MB per file.
The home page shows no tiers or prices, so the cost cannot be judged from it.
Nothing is said about where the company sits or who owns it.
Right for

Not stated by the vendorPlans sit on a separate page and no tiers appear on the home page; a preview label is shown
Practice and stem app for browser, desktop, iPhone, iPad and Android
Ranked #6 of 12 in Best AI Stem Separation Tools in 2026.
Free tierPricing on requestNorth America
Moises Systems, Inc. trades as Music AI from Salt Lake City, Utah, and ships apps for browser, desktop, iPhone, iPad and Android. That reach suits rehearsal use, where one song moves between devices.
The catch sits in the pricing table, which only opens after login, so a team cannot budget before signing up, and the free tier restricts both uploads and features.
What stands out
Mobile and desktop apps
Monthly upload cap
Practice tools
Where it costs you
Paid prices appear only once you have registered an account
The free tier caps monthly uploads without printing the number
Right for
Musicians who want practice tools on phone, tablet and desktop

United StatesLimited monthly uploads at no cost; full use needs a subscription whose prices appear only after login
Pay-per-module audio API with SDK, storage and enterprise options
Ranked #7 of 12 in Best AI Stem Separation Tools in 2026.
Published pricingNorth America
Billing is per module, for example a stated rate per minute for AI music detection, so costs track usage instead of a seat. Professional adds ten concurrent jobs, 100GB of permanent storage and a 5% module discount.
Larger buyers can ask about a dedicated CDN, bring-your-own storage and a private model. It is an integration product, and casual listeners will find it more than they need.
What stands out
Per-module billing
Embedded SDK
Private model option
Where it costs you
Pay as you go keeps files for only 48 hours and runs two jobs at a time.
Business pricing is volume-based and must be requested.
The Professional credit is described as a limited offer, so its value may change.
Right for

United StatesPay as you go from zero with per-module usage rates, a Professional monthly plan and a Business tier quoted on request; prices published
Stem and dialogue separation sold as studio tools and developer API
Ranked #8 of 12 in Best AI Stem Separation Tools in 2026.
Pricing on requestNorth America
AudioShake reaches beyond music into film and speech work, with dialogue and effects separation, speech denoising, dereverberation and real-time separation named.
That breadth is its pitch to media teams. For a plain stem buyer it is harder to size up: costs and limits are absent from the home page, and the product list reads like a catalogue rather than one tool.
What stands out
REST API and SDK
Dialogue isolation
Lyric alignment
Where it costs you
Budgets cannot be set from the front page, which lacks any price.
The page states no usage, rate or file-size limits.
Products are split across several names, which makes it harder to see which one covers a given job.
Right for
Media teams separating dialogue, music and vocals through an API
Wrong for
Hobbyists wanting a priced plan they can read today
United StatesNo prices shown on the home page; the Studio offering starts at no cost with a try button
Voice platform whose stem splitter sits among its online audio tools
Ranked #9 of 12 in Best AI Stem Separation Tools in 2026.
Free tierPublished pricingElsewhere
The plan table is detailed, with credits, conversion length and audio-tool minutes at each tier from Free up to Enterprise. Stem splitting is included at the Free level, which lowers the cost of trying it.
The weakness for this category is focus: the page does not list stem types or quality, so you are judging a voice platform that happens to include a splitter.
What stands out
Credit-based plans
Vocal Remover
Stem splitter on free plan
Where it costs you
Stem splitting is one tool inside a voice product, not the focus of the plan.
Plans are measured in credits and tool minutes, which makes the real cost per song harder to work out.
The company's country and ownership are not given.
Right for
People already using voice tools who want stem splitting in the same account
Wrong for
Users who want a dedicated separation product with documented stem types
Not stated by the vendorMonthly credit plans from a zero-cost level to custom Enterprise, with yearly billing offered; dollar prices published
Two-stem extraction, reverb removal and YouTube splitting on Spleeter
Ranked #10 of 12 in Best AI Stem Separation Tools in 2026.
Published pricingElsewhere
The offer is narrow and clear on the page: a two-stem split, reverb removal and YouTube input, with the Spleeter project named as its base.
Anyone needing more than vocals and accompaniment should look elsewhere on this list. Because prices, limits and the free upload terms are all missing, it works best as something to try, not something to budget for.
What stands out
Built on Spleeter
YouTube splitting
API section
Where it costs you
The home page describes two-stem separation, so more granular stems are not shown.
No prices, limits or hosting model are stated.
The contents of the linked free upload option are not described.
Right for
Users wanting a vocal and backing split straight from a YouTube link
Wrong for

MIT-licensed separation model you install and run yourself
Ranked #11 of 12 in Best AI Stem Separation Tools in 2026.
Open sourcePricing on requestElsewhere
StemRoller builds on this model, so going to the source gives you control: pip, conda or Docker installs, a Colab notebook and a Hugging Face demo are linked.
The default is four stems, the fine-tuned version trades roughly fourfold speed for quality, and the six-source option adds guitar and piano. Archival means you own any maintenance, and nobody offers support.
What stands out
MIT licence
Archived repository
Six-source model
Where it costs you
The repository is archived and read-only, so fixes will not arrive there.
The six-source model comes with a maintainer warning about piano quality.
The fine-tuned model is about four times slower than the default.
Right for
Developers who want a modifiable model they can run on their own hardware
Wrong for
Non-technical users who want an app with support
Not stated by the vendorOpen source under the MIT licence; installed on your own machine through pip, conda or Docker
Gaudio Lab product that splits music into instruments and vocals
Ranked #12 of 12 in Best AI Stem Separation Tools in 2026.
Pricing on requestElsewhere
Gaudio Studio is listed on the Gaudio Lab home page with a one-line description and nothing else that we could verify there. That makes it a product to enquire about, not one to evaluate from a browser.
Treat any claims about quality, formats or speed as unconfirmed until the vendor supplies them, and ask for pricing early in any conversation.

An AI stem separation tool analyses a mixed audio file and returns separate tracks for vocals and instruments, as downloads, plugins or an API for editors. Feature lists look alike, so we would settle these points one at a time instead.
01
Check who publishes a price
Prices are public at 7 products (LALAL.AI, Fadr, StemRoller, RipX DAW, Music AI, Voice.ai, Splitter AI) and on request at the remaining 5, so budget time for quotes if your favourite is in that second group.
02
Weigh the vendor's home jurisdiction
The vendors on this page are based in 3 countries (Elsewhere 8, North America 3, Europe 1). The country of the contracting company sets which authorities can ask it for your data, whatever the hosting region.
03
Decide if open source matters
Source code is available for Demucs. Running it yourself swaps the licence fee for your own upkeep.
How AI stem separation tools charge: minutes, credits or modules
Price units in this market differ so much that headline plans cannot be compared directly. LALAL.AI counts minutes, and each file's length is multiplied by the number of stem types you select, so a four-stem job costs four times what a one-stem job does. Voice.ai sells credits and audio-tool minutes by tier, while Music AI bills per module with rates such as a per-minute fee for music detection.
Fadr takes a flat monthly or yearly price and instead limits upload length and stem choice. Before choosing, write down how many songs you split a month and how many stems you want from each, then convert every vendor's unit to a cost per finished track. The result often reverses the order suggested by sticker prices.
Convert each vendor's quota into a cost per song for your usual stem count
Check whether a queue is relaxed or fast, because LALAL.AI separates the two
Look for top-ups or module rates that apply once the monthly allowance runs out
Which stems you actually receive from AI stem separation tools
A four-stem result of vocals, drums, bass and everything else is the baseline, and it is what StemRoller and the default Demucs model give. Anything finer is where products differ. Fadr keeps guitar, piano, strings, wind, kick and snare for Plus, PhonicMind claims up to eight usable stems, and RipX DAW goes down to individual notes.
Splitter AI describes a two-stem split, which suits karaoke but nothing more. Demucs documents its own weak spot: the README flags piano in the six-source model as unfinished. Decide which instrument you need isolated, then test that stem on a track you know well, not on the vendor's demo, because bleed shows up fastest on dense mixes.
Name the single instrument you most need isolated and test only that stem
Confirm whether the stem sits on the free plan or a paid one
Listen for bleed between stems on a dense recording
Local or hosted: where stem separation runs
Some tools process audio on your own computer and others upload it. LALAL.AI runs locally in its desktop app and inside a DAW through its VST plugins, StemRoller is a desktop download for Mac and Windows, and Demucs installs through pip, conda or Docker. Fadr, Moises and Music AI are hosted, with Moises also offering desktop and mobile apps.
Local running keeps unreleased material off third-party servers and removes upload size caps, but it ties speed to your hardware, and StemRoller's Windows build is aimed at CUDA graphics cards. Hosted services spare you the setup but add storage rules of their own, such as Music AI keeping files for 48 hours on its pay as you go level.
Decide whether unreleased audio may leave your machine at all
Check the graphics hardware requirement before downloading a local app
Read the storage period for uploaded files on hosted plans
Consumer apps and developer APIs in AI stem separation tools
Buying for a person and buying for a product are separate decisions here. Moises and Fadr are built for individual musicians, while Music AI and AudioShake present REST APIs, SDKs and developer documentation. LALAL.AI and Fadr sit in between, since each reserves API access for its higher plan, Pro and Plus respectively.
If you plan to put stem separation inside your own app, check concurrency, storage and what the vendor says about volume pricing, because Music AI limits pay as you go to two concurrent jobs. Also bear in mind that Moises and Music AI are the same legal entity, so choosing both gives you one supplier, not two, and one set of terms to read.
Check which plan unlocks the API and what its concurrency limit is
Ask for volume pricing in writing before building on a usage rate
Confirm who the legal entity is when two brands look separate
What goes wrong most often when buying AI stem separation tools software
Comparing monthly prices without converting each vendor's minutes, credits or modules into a cost per finished song.
Assuming a six-stem model separates every instrument well, when the Demucs README itself flags piano as unreliable.
Choosing a project-critical tool whose maintainers have stopped, such as the archived Demucs repository, without planning who maintains it.
Uploading unreleased tracks to a hosted service without reading how long files are stored.
