Party checklist
| Before the party | Why |
|---|---|
| Make the tracks the day before | The free tier is 1 full split a day; credits cover a whole playlist |
| Listen to the whole instrumental once | Quiet parts can show faint vocal leftovers |
| Shift the key if the chorus is out of reach | Two semitones down makes most songs easier for most voices |
| Keep the Vocals file too | Play it quietly as a guide if people forget the melody |
| Save the lyrics | Read from your phone, or make a lyric video to show on a TV |
Change the key to fit your voice
Most karaoke trouble is a song pitched for a different voice. After the split, open the free pitch changer, load the instrumental and move it in semitones without changing the speed. It runs in your browser, so the file is not uploaded again.
| If the song is… | Try |
|---|---|
| Sung by a higher voice than yours | Down 2 to 4 semitones |
| Sung by a lower voice than yours | Up 2 to 3 semitones |
| Male song, female singer (or the reverse) | Up or down 4 to 5 semitones |
Hear a real separation
A real result from the engine behind the tool. For karaoke you only need the 2-stem mode: Vocals and Instrumental.
Backing vocals usually go with the lead vocal. Songs with heavy reverb on the voice can leave a faint echo; it is rarely noticeable through a party speaker.
Frequently asked questions
Can I split a song without uploading it, for free and without limits?
Yes. Choose In your browser above the drop zone. The same Demucs htdemucs model runs on your own device, so the file is never uploaded and there is no daily limit, for 2 or 4 stems and songs up to 8 minutes. The first run downloads the 172 MB model once. It is slower than the server, usually a few minutes for a 3-minute song, and works best in a recent Chrome, Edge or Safari on a laptop or desktop.
How do I make a karaoke version of a song for free?
Upload the MP3 to the tool on this page with 2 stems, wait under a minute and download the Instrumental. It is free for 1 full split a day, up to 10 minutes per song, with no sign-up.
Can I do it on my iPhone or Android phone?
Yes. It runs in Safari or Chrome on the phone. Pick the MP3 from Files or Downloads, and the instrumental saves back to Files or Downloads.
Can I change the key of the karaoke track?
Yes. Open the free pitch changer, load the instrumental and shift it by semitones. It keeps the tempo the same and runs in your browser.
Will the vocals be completely gone?
Usually almost completely. Some songs leave a faint trace in quiet parts, especially with heavy reverb. Listen once before the party.
I need ten songs for tonight. Can I do more than one?
The free tier is 1 full split a day. Beyond that, a one-time credit pack covers more songs without a subscription; each started 5 minutes of audio costs 30 credits.
Can I use a YouTube or Spotify link?
No. Upload an audio or video file you have on your device. Use songs you own or have the right to use.
