Turn Any Video Into a Synced Karaoke Track — Free and Offline

Most "get me a karaoke version" options come with a catch: a limited catalog, a per-song fee, or an online tool that wants to upload your file to someone else's server first. If you already have a video of the song — a music video, a live recording, a lesson clip — you have everything you need. You just don't have an easy way to pull it apart.

That's what OraKara does. Point it at a video, hit Go, and it hands you back a synced player with the vocals and the instrumental separated into independent tracks — running entirely on your own machine.

What happens when you hit Go

OraKara runs a three-stage pipeline on the video you give it:

• Extract — pulls the audio out of the video.
• Separate — splits that audio into a vocals track and a backing/music track.
• Unduck — repairs the backing track anywhere the original mix had quietly ducked the music down under the vocals, so the instrumental you get back doesn't have a mysterious dip every time someone sings.

The result opens straight into a player where the muted original video plays back in sync with both separated tracks, each with its own volume and mute — sing over the backing track, or solo the vocal as a reference while you play along.

Built for practicing, not for producing

OraKara isn't trying to be a professional stem-splitting suite. It's built around one job: take a video you already have and make it practicable — karaoke, vocal warm-ups, learning a part on an instrument by isolating the vocal line, or just hearing a mix broken apart. Queue up more than one video at a time and it works through the batch on its own with a configurable concurrency limit, which matters if you're prepping a whole setlist rather than one song.

No cloud, no subscription, one sign-in

Everything runs on-device — there's no upload step and nothing to pay for, ever. Activating it takes a single free Google sign-in on your machine, once; after that it's unlocked on that machine for good, with no card, no trial, and no renewing anything.

Browse a video. Hit Go. Get a synced karaoke player.

If you've got a video and a song stuck in your head that you want to practice, that's really the whole pitch.
