Singlio Audio Extension

Sing karaoke with any YouTube video - change the key and sing along with mic effects, all from your Singlio page.

Singlio Audio Extension turns any YouTube video into a karaoke machine — right from your Singlio event page. It captures the song playing in your YouTube tab, lets you change the key higher or lower to fit your voice, and adds studio-quality effects to your microphone like reverb and echo. You get separate volume controls for the music, your mic, and the overall mix so everything sounds balanced. All controls are inside the Singlio app — no separate window to learn. Get started in three steps: 1. Go to https://singlio.app and create a free account 2. Create an event and add YouTube videos to your queue 3. Open your event and hit "Start" to sing — change the key, adjust volumes, and add effects right from the app Install it if you run karaoke events on Singlio, practice singing along to YouTube videos, or teach vocals and need to adjust song keys on the fly. No extra apps, no downloads, and your audio never leaves your browser.
