AI vocal removal and stem splitting, paid by the minute with no subscription
Beginner API
What is StemSplit?
StemSplit is an audio editing tool. StemSplit strips vocals from songs and separates them into four or six stems, processing uploads and YouTube or SoundCloud links in under a minute. It sells prepaid credits rather than subscriptions, with a free five minutes on signup and an API for developers.
StemSplit is an AI audio separation service built around a single, focused job: taking a finished song and pulling it apart into usable pieces. Drop in an audio file (the site lists mp3, wav, flac, m4a, ogg, webm, aac, opus, aiff, aif and wma, up to 100MB) and the tool returns a vocals stem alongside an instrumental, typically in 30 to 60 seconds. Paying users can go further and request separation into four or six stems, adding drums, bass, and on the six-stem option piano and guitar. The workflow is deliberately shallow. Users can upload a file directly or paste a YouTube or SoundCloud link, and the site handles the download step on the user's behalf rather than forcing a two-stage process. Processing begins the moment a file lands, which keeps the loop tight but also means there is no output picker on the main upload page: the split runs before a choice is offered. Results, not just processing, require an account, so the free five minutes are really a way to see the quality before committing to credits. StemSplit is aimed at three broad audiences the site names explicitly: singers who want backing and karaoke tracks from commercial releases, DJs and producers building mashups who also get beat grids, Camelot key notation and a one-click Rekordbox XML export, and content creators who need instrumental beds for video, podcasts and streams. A REST API with webhooks, plus guides for n8n, Zapier and Make, serves developers who want to put separation inside a larger pipeline. Where it differs from the subscription-separator crowd is the billing model. Credits are bought in blocks (10, 30, 100 or 300 minutes) at a per-minute rate that falls as the block grows, and the site states credits do not expire. That suits occasional users far better than a monthly plan, particularly anyone who needs a handful of tracks before a gig or a project. Files are deleted after 48 hours and the site says audio is not used for model training.
How do you use StemSplit?
1Create an account to unlock the free minutes
Signing up with an email grants 5 free minutes of processing and is required before any stem can be downloaded. No payment card is requested at this stage.2Upload a file or paste a streaming link
On the homepage, drop an audio file up to 100MB or use the YouTube and SoundCloud options if you would rather supply a URL. Processing kicks off as soon as the input is accepted.3Let the split finish and review the stems
Most tracks complete in 30 to 60 seconds. The default output is a vocals stem plus an instrumental; paid credits open up 4-stem and 6-stem separation with drums, bass, piano and guitar.4Buy a credit pack to keep working
The homepage pricing block lists four one-off packs from 10 to 300 minutes. Credits do not expire, so a larger pack prices lower per minute without wasting unused time.5Try a DJ or karaoke workflow
DJs can pull beat grids, Camelot keys and a Rekordbox XML export for harmonic mixing, while singers can use the karaoke path to build backing tracks from commercial releases.6Wire separation into your own tooling
Developers get a REST API with webhooks, a full reference, and setup guides for n8n, Zapier and Make. API calls draw on the same credit balance as the web app.
Pros and cons
Pros
- Credit packs never expire, so occasional users are not locked into a recurring billAI
- Per-minute cost drops from $0.20 on the 10-minute Starter pack to $0.10 on the 300-minute Studio packAI
- Accepts YouTube and SoundCloud URLs directly, removing the manual download stepAI
- DJ Mode adds beat grids, Camelot notation and one-click Rekordbox XML exportAI
- Free five minute allowance on signup with no credit card, enough to judge output quality on real tracksAI
Cons
- Processing starts the moment a file lands, so there is no chance to choose a 4-stem or 6-stem output before the job runsAI
- Results cannot be downloaded without an account, which is a hard gate even for a quick testAI
- 100MB upload ceiling will exclude long DJ sets and full album-length recordingsAI
- Accuracy of 95%+ is the vendor's own figure and will vary on dense mixes or heavily processed vocalsAI
- No offline or desktop option listed, so separation depends entirely on the web serviceAI
