Cinematic lyrics
Every word, breathing.
A custom wgpu lyrics engine: SDF glyphs light up word by word, every line rides its own spring, and layered Gaussian blur adds depth of field. Duets, background vocals, interlude breaths, translations and romanization — all there.
- Word by word
- Syllable-timed highlighting, with glow and lift on held notes.
- Spring physics
- Every line on its own spring, cascading as it scrolls.
- Duets & harmonies
- Duet lines align right; background vocals shrink and fade.
- Best source wins
- AMLL TTML, QQ Music QRC and NetEase YRC, picked automatically.
