Vocal Remover and Karaoke Video Maker
Two jobs, one upload. The first is the ordinary one: take your song and pull it apart into a vocal track and an instrumental, so you can sing over the backing, practise a part, or hand someone a version with no lead line. The second is the one people actually want from a karaoke tool — the instrumental with the words on screen, timed to the singing rather than scrolling at a fixed speed.
The karaoke mode does more than strip the vocal. It builds a video: a gradient background, the song title shown before the first line, and lyric lines appearing in time with the vocal. You choose the shape (widescreen or vertical) and one of five backgrounds. You can also paste the lyrics before you start, which is the single biggest improvement available to the spelling — the transcriber hears the words, but you know them.
What this tool does
- VdoBloom's vocal remover splits an uploaded song into two tracks — the vocals and the instrumental — from one file of up to 25 MB and eight minutes.
- Karaoke video mode renders the instrumental with the lyrics on screen, timed to the singing rather than scrolling at a fixed rate.
- The karaoke video can be rendered in 16:9 or 9:16, on one of five gradient backgrounds, and the song can be up to six minutes long.
- Pasting the lyrics before you generate improves the spelling of the on-screen words; the tool refuses lyrics in a script its fonts cannot draw, before anything is charged.
- The song title is shown on screen before the first lyric line, like a title card.
- New accounts start with free signup credits, one-time credit packs never expire, and subscriptions are also available for a monthly allowance.
Karaoke timing is the hard part, and it is done for you
A karaoke video that drifts is worse than no video, which is why the lyric timing here is derived from the vocal rather than from a fixed interval. The words are transcribed from the audio and placed against the singing, so a line waits for the singer instead of arriving on a metronome. That matters most in tracks with a rubato verse or a spoken intro, where a fixed timer falls apart within a bar.
The practical consequence is that the quality of the backing vocal separation and the quality of the lyric timing are related. If the instrumental still carries a ghost of the lead voice, the transcriber still hears it — usually a good thing, since it keeps the timing accurate. If a passage has no vocal at all, for example a long instrumental break, expect the text to sit still until the singing returns.
What to do with the two-track split
The vocal remover mode is not only a karaoke step. A singer uses the instrumental to rehearse in the real key. A producer pulls the vocal to hear how a phrase is delivered, or to sample a phrase with the music gone. A teacher hands a student the backing and keeps the reference. Anyone checking a mix can listen to the instrumental alone and hear whether the arrangement still holds up without the voice in front.
Both tracks download separately, so you can take them straight into any editor. The one caveat worth repeating is that separation is inference rather than a return of the original studio parts: a wide-stereo mix with lots of reverb gives the model much less to work with than a dry, centred vocal does.
How it works
1.Upload the song and confirm the rights
MP3, WAV or M4A up to 25 MB, eight minutes long. You confirm this is your recording or that you have permission to use it before the separation runs.
2.Choose Vocal remover or Karaoke video
Vocal remover returns the two tracks — vocal and instrumental — as separate downloads. Karaoke video renders the instrumental with the words on screen instead.
3.For karaoke: title, background and shape
Type the song title for the opening card, pick one of the five gradient backgrounds, and choose 16:9 for a screen or player, 9:16 for a phone.
4.Paste the lyrics, then generate
Dropping the real lyrics into the box fixes most spelling errors before they happen. Then render the video and watch a verse or two to check the timing against the vocal.
Frequently asked questions
How good is the vocal removal?
Separation is a best-effort process on any tool, including this one. Songs with a centred lead vocal over a wide backing separate cleanly; dense mixes, heavy reverb on the voice, or a vocal that sits off-centre leave artefacts — usually a faint ghost of the voice or a slightly hollow instrumental. Listen to the result before you rely on it, especially if you are recording over the top.
Can the karaoke video include the original backing vocals?
No — the point of the karaoke render is the instrumental with the lead line removed. If you want harmony or backing vocals kept while the lead disappears, that needs a stem separation rather than a two-track split, and even then which parts survive depends entirely on how the original was mixed.
Why do I have to paste the lyrics myself?
Because the on-screen words are transcribed from the audio, and transcription hears what it hears — names, slang and non-English words are the usual casualties. Pasting the correct lyrics overrides that. If you leave the box empty you still get a karaoke video with timed lines, just with more spelling to fix.
How long can the song be, and how long can the karaoke video be?
The uploaded song can run to eight minutes and 25 MB for a plain vocal removal or stem split. A karaoke video is capped at six minutes, so a longer track needs trimming first. The form tells you when the file is too long before you start rather than after.
Is karaoke available in my language?
The on-screen text can only be drawn in scripts the renderer has fonts for. If you paste lyrics in a language whose letters cannot be drawn, the tool refuses the job up front instead of wasting the run — the honest answer is to try it with a line or two of your language before you upload a whole song.
Can I use the instrumental I get for a recording or a release?
You must own the song or have permission to use it — that confirmation is part of the form, and it carries through to whatever you do with the output. Recording a cover of a song you do not own is a licensing question in your jurisdiction, and the tool does not settle it for you.
Is it free to try?
New accounts start with free signup credits, so you can test a song end to end before spending anything. After that, work runs on credits: one-time packs never expire, and subscriptions exist for a monthly allowance.
