Fast start

Drop an MP3 up top → click Play.
Pick a Mode and Palette.
Use YouTube Preset if you want a safe baseline.

Recommended “safe” YouTube settings

1920×1080, 30 FPS
VP8, 4 Mbps video, 128–160 kbps audio
Comp: Auto to prevent stutter while recording

Best quality without stutter

Lower Scale first (0.85× helps a lot).
Reduce Particles, then reduce Trails.
Keep Bloom moderate if recording drops frames.
Try VP8 for smaller files and compatibility.

Privacy

Audio is loaded from a local browser object URL.
Analysis uses Web Audio (analyser) + Canvas rendering.
No upload is needed to use this tool.

Troubleshooting

No sound / won’t play: click anywhere once, then click Play again (browser gesture requirement).
Recording stutters: set Comp: Auto, use 30 FPS, and drop Scale to 0.85×.
File too large: lower video bitrate to 2–4 Mbps and prefer VP8.
Trails too strong: reduce Trails (it controls persistence now).
