About Karaoke Studio

Karaoke Studio is a lightweight recording studio that runs entirely inside your browser. No sign-ups, no tracking cookies, and no waiting for cloud uploads. Drop in an instrumental track, hit record, and export your mix.

Zero Servers. Zero Databases. 100% On Your Device.

Most audio apps upload your voice to cloud buckets. Karaoke Studio doesn't even have a backend database. All audio processing, reverb effects, and mix rendering happen locally on your computer using the Web Audio API. Drafts stay saved in your browser's local storage (IndexedDB), and when you export, the file downloads straight to your hard drive. We never hear, touch, or store your tracks.

Bluetooth & Hardware Mic Sync

Wireless headsets introduce delay. Use the offset slider to manually nudge vocal tracks forward or backward in milliseconds to lock in with the beat.

Offline Drafts

Save recordings as browser drafts without creating an account. Close the tab, come back tomorrow, and pick up right where you left off.

Master Reverb

Apply real-time spatial room reverb to vocal takes so they sit naturally over the backing track before final bounce.

Direct MP3 & WAV Export

Render and download high‑quality MP3 or lossless WAV files directly in the browser with a single click.
