Feed your music into GENAU

GENAU builds its world from the words it hears. Browsers only let a page listen to a microphone, so to use the lyrics of whatever plays on your computer (Spotify, Apple Music, YouTube…) you route the computer's sound into a virtual microphone. One-time setup, about five minutes. Use Chrome or Edge, online (their speech recognition runs in the cloud).

Mac

Install BlackHole 2ch, a free virtual audio cable: existential.audio/blackhole (or brew install blackhole-2ch). Restart if asked.
Open Audio MIDI Setup (Spotlight → “Audio MIDI”). Bottom-left + → Create Multi-Output Device. Tick your speakers or headphones first, then BlackHole 2ch; turn on Drift Correction for BlackHole. This way you hear the music and the game hears it too.
System Settings → Sound → Output: choose the Multi-Output Device.
In Chrome on the GENAU page: click the icon left of the address → Site settings → Microphone → BlackHole 2ch. Reload.
Play a song with clear vocals, click into GENAU, press V if voice is off, L to pin the language (AUTO tries German and English and keeps the one that understands more).

The Mac's volume keys don't work on a Multi-Output Device: set the volume in the music app. To undo, switch Output back to your speakers.

Windows

Quick way (if your sound card has it): Stereo Mix

Settings → System → Sound → More sound settings → Recording tab. Right-click the empty area → Show Disabled Devices.
Right-click Stereo Mix → Enable.
In Chrome/Edge on the GENAU page: icon left of the address → Site settings → Microphone → Stereo Mix. Reload.

No Stereo Mix? Use VB-Cable (free)

Install VB-Audio Virtual Cable (run the setup as administrator, then restart).
Settings → System → Sound → Volume mixer: set your music app's output to CABLE Input.
To still hear it: More sound settings → Recording → CABLE Output → Properties → Listen → tick Listen to this device, playback through your speakers.
In Chrome/Edge: Site settings → Microphone → CABLE Output. Reload.

Tips

Sung words with clear vocals work best; rap and spoken word work great. Pure instrumentals give nothing (press B for beat syllables instead).
The V meter in the bottom bar shows whether sound is arriving.
Your own voice works without any of this: just allow the microphone.
