Separate the vocals from the instrumental online

You upload a file you already own, the model splits the vocal off, and in 2 to 3 minutes the instrumental plays in your browser. Nothing to install, nothing to configure, no graphics card.

What runs when you upload the file

The separation is done by UVR-MDX-NET-Inst_HQ_3 — the same model file Ultimate Vocal Remover ships with. Not an imitation, not something "similar": that one, running on a server instead of on your machine. The difference isn't the quality of the separation; it's who installs and configures it, and what comes out the other end.

Takes mp3, wav, m4a, ogg and video, up to 400 MB per file.
There is no link field. The file has to come off your own computer — you can't paste a video address and have it fetched.
It takes 2 to 3 minutes per song with the cloud accelerator on, and over 10 minutes when it is down.

What you get to take away — the part nobody writes down

This is what separates a vocal remover from a karaoke generator, and it's worth reading before you make an account:

What you want to do	Can you?
Hear the instrumental on its own, in the browser	yes, there's an "instrumental only" toggle
Download the instrumental as an audio file	yes, on Pro — "download the instrumental", in the song menu
Download the isolated vocal	no — the separated vocal is never kept: it is used to transcribe the lyrics and deleted afterwards
Download a vertical video with the instrumental and the lyrics	yes, recorded as you sing
Download the UltraStar .txt score sheet	yes, named "Artist - Title"

So be straight with yourself: the instrumental does come out as a file here — but only on Pro (US$ 3.99 a month): every song menu has "download the instrumental", and the file arrives named "Artist - Title (instrumental).mp3", the same 192k MP3 the server keeps. On Free the button is there with a Pro badge and takes you to the plans page — the instrumental plays, it just doesn't download. And if your problem is that the file can't leave your machine, no plan fixes that: UVR on your own machine does it for free and nothing is uploaded anywhere.

What a plain remover doesn't do

A separator hands you two files and its job is done. After the separation, this is what keeps happening on its own:

The published lyrics are looked up and checked against the audio. If they match, they're what you get; if they don't, the page says so and uses what the machine heard instead.
Every syllable gets a start and a duration — that's what makes the lyrics move in time instead of sitting still on screen.
Every syllable gets a pitch, and that's what lets the microphone hear you and the score tell you whether you went sharp or came in late.
Two singers, two separate microphones, each with its own sensitivity.
A lyrics-and-timing editor inside the site, with the server keeping a copy of the original file before the first save.

It's the same machine work as always — stripping the vocal — except it doesn't stop at the file.

When this is the wrong tool

If the file can't leave your machine. It uploads to our server, and the heavy part may run on a GPU service in the United States. That reason is legitimate and final: no cloud service answers it, and ours doesn't either.
If you want the instrumental as a file and don't want to subscribe. The download exists, but it's a Pro feature. For a single song, UVR on your own machine is cheaper than a month.
If you want the isolated VOCAL. That one doesn't leave here on any plan. The separated vocal is used to transcribe the lyrics and deleted right after — it isn't stored, so there is nothing to download.
If the vocal is screamed, heavily distorted or recorded live. The separation will still run, but the transcription gets words wrong in exactly those cases. On a studio recording with clear diction the result is good; on hardcore, it isn't.

And the caveat that holds for any separator, ours included: separation never adds quality. If the source file is poor, the instrumental is poor plus separation artefacts.

Price, no small print

Free: 3 songs a month, 900 MB, no card. The vertical video comes out watermarked, and the library keeps the 3 most recent songs unlocked.
Pro, US$ 3.99 a month: 30 songs a month, 4 GB, the video comes out clean at 1080×1920, and the instrumental downloads as a file.

Neighbouring reads

If your instrumental is coming out muddy and you want to know why before uploading anything, start with why phase inversion sounds muffled. And if your end goal isn't the instrumental but actually singing, the page you want is the karaoke track page.

Frequently asked questions

Can I separate vocals from a song online without installing anything?

Yes. You upload the file and the separation runs on the server, with the same model Ultimate Vocal Remover uses (UVR-MDX-NET-Inst_HQ_3). It takes 2 to 3 minutes per song with the cloud accelerator on, and over 10 when it is down.

Can I download the separated instrumental as a file?

Yes, on the Pro plan (US$ 3.99 a month). The song menu has “download the instrumental” and the file comes out as “Artist - Title (instrumental).mp3”. On the Free plan the button is shown with a Pro badge and leads to the plans page: there the instrumental plays in the browser and is baked into the vertical video, but never becomes a file. The isolated vocal is not downloadable on any plan — it is not kept on the server.

Which model is used to remove the vocals?

UVR-MDX-NET-Inst_HQ_3, the same model file distributed with Ultimate Vocal Remover. The separation is the same; what changes is that you install and configure nothing.

What happens to the file I upload?

It stays in your library on our server, and the heavy part of the processing may run on a GPU service in the United States. If the file can't leave your machine, use a local tool — that's the right answer and we have no way to meet it.

How much does it cost?

The Free plan does 3 songs a month, gives you 900 MB and asks for no card; the vertical video comes out watermarked. Pro is US$ 3.99 a month, does 30 songs a month, gives 4 GB and the video comes out clean.
