All Mixer! - Karaoke and Live Vocal/Instrumental Separation

Volume boost and vocal/instrumental mixing on any site, plus synced lyrics on YouTube and YouTube Music.

🎤 Turn your browser into a karaoke machine. All Mixer! separates the vocal from the instrumental of any song, live, so you can turn the singer down to sing along, or turn the band down to hear the voice. 🎚️ SEPARATE MODE • Mix the vocal and the instrumental with their own sliders. • One-click presets: Karaoke, Half karaoke, A cappella. • Four separation models, from a fast default to a best-quality one. • Split instrumental: give drums 🥁, guitar 🎸, bass and piano 🎹 their own levels. • Runs on your GPU (WebGPU) on your own computer. Nothing is uploaded. 🔊 BOOST AND PITCH • Global volume up to 600 %, with a limiter that keeps the sound clean. • Shift the pitch up or down by up to 6 semitones. The speed stays the same. • Works on any website with a video or audio player. 📝 SYNCED LYRICS • Lyrics follow the song on YouTube and YouTube Music. • Floating panel, karaoke overlay, or the native Lyrics tab on YouTube Music. 💡 GOOD TO KNOW • Separate mode needs a computer with a GPU (WebGPU). • Separate mode delays the sound by about 2 seconds. The picture is delayed by the same time so they stay in sync. A longer delay limit gives a cleaner split. • The higher quality models are a one-time download from Hugging Face. 🔒 PRIVACY • Audio never leaves your computer. The extension only contacts LRCLIB (for lyrics) and Hugging Face (for models). • Policy: https://github.com/sriv95/All-Mixer/blob/main/PRIVACY.md 💻 OPEN SOURCE • Free and open source: https://github.com/sriv95/All-Mixer All Mixer! is not affiliated with, endorsed by or sponsored by YouTube or Google.
