How to make a karaoke track from an mp3

Open the song and pick the Karaoke preset. It mutes the vocal stem, so when the split finishes you're left with the band. If you'd like the singer there as a guide while you learn the words, pick Sing along instead. It keeps the vocal in, turned down to about a third. Sing the chorus once through. If the top note is a strain, move the pitch down one semitone at a time until it sits where your voice is comfortable. The speed doesn't change when you do this. Loop the phrase that keeps tripping you up, and slow it a little if the words come too fast. When it feels right, export the mix as WAV or MP3 with the new key applied, and take it to rehearsal or karaoke night. One thing to know: not always. The lead goes with the vocal stem, but harmonies and group vocals often stay in Other. Your song isn't uploaded.

A full mute, or a quiet guide

The Karaoke preset mutes the vocal stem and leaves the band. That is the track you want once you know the song. While the melody is still new, Sing along is the kinder start. It keeps the vocal in the mix at about a third, loud enough to follow and quiet enough that you can hear yourself. Sing the chorus once. If the top note strains, move the pitch down one semitone and sing it again. The speed does not move when the pitch does, so you are not also fighting a faster or slower band. Moving pitch without speed has a longer walk-through on change the key of a song.

A phrase that still trips you can be looped and slowed a little. Bring the speed back up before you export, unless you want the rehearsal file slower on purpose. When you export the mix as WAV or MP3, apply the speed and pitch, and the file that leaves the browser is already in your key.

What still sounds like the singer

Not always. The lead goes with the vocal stem, but harmonies and group vocals often stay in Other. A harmony stack, a double, or a gang vocal on the last chorus may still sit in Other. Singers sometimes call the vocal-muted result a minus one. Lower Other on the sections where they get in the way.

Reverb printed on the vocal can leave a faint ghost in Other after the stem is muted. Live rooms and heavily effected vocals do this the most. A dry studio vocal disappears more cleanly. This page will not put words on the screen. Keep them on a stand or a second screen. There is no support for a pasted video link. Open a file you have: mp3, wav, flac, m4a, or an mp4, up to 20 minutes.

Take the file to the room

Export, then play the file at rehearsal or on karaoke night from a phone or through the PA. The pitch you set is in the file, so you do not have to find the semitone again on someone else's player. If you only wanted the lead gone and the original key is already comfortable, the vocal page starts from the same mute. This page assumes you will also move the song to where your voice sits. Your song isn't uploaded.

Questions

How do I make a karaoke version of a song?

Open the song and pick the Karaoke preset. It mutes the vocal stem, so when the split finishes you have the band without the singer.

Can I change the key to fit my voice?

Yes. Move the pitch down or up one semitone at a time; the speed doesn't change. The exported file keeps the new key.

Can I keep the original singer quietly as a guide?

Yes. The Sing along preset keeps the vocal in the mix at about a third of its level, loud enough to follow and quiet enough to hear yourself.

Does it show the lyrics?

No. It makes the backing track, not a lyric video. Keep the words on a stand or a second screen.

Can I make karaoke from a video link?

No. Open a file on your device: mp4 video files work, along with mp3, wav, flac, and m4a, up to 20 minutes.
