​
Volume Tips

Start with all volumes at 50-70% and adjust from there. Too many effects at 100% can become overwhelming.
All volume settings are automatically saved to your browser’s localStorage and persist between sessions.

​

​
Auto DJ Technical Details

Auto DJ transitions include a sophisticated crossfade effect:
  1. Low-pass filter sweeps down to 300Hz over 2 seconds (muffling effect)
  2. Changes occur during the muffled state
  3. Filter sweeps back up to 1200Hz over 2 seconds (clarity returns)
This creates seamless, professional-sounding transitions between musical keys.
Try ATMOSPHERE mode for your first session. It provides the right balance between automation and control.

​
Background Customization

Personalize your visual experience with background image controls.

​
Default Backgrounds

LoFi Engine includes 10 built-in background images:
  • Navigate using ←/→ arrow keys
  • Click the left/right arrow buttons in settings
  • Backgrounds range from serene landscapes to urban scenes

​
Custom Backgrounds

1

Upload Your Image

Click the + button in the background section of settings. Select one or multiple image files (JPG, PNG, etc.).
2

Image Processing

Images are converted to data URLs and stored in your browser’s IndexedDB. This allows them to persist between sessions without server uploads.
3

Navigate Your Collection

Custom backgrounds are added to the rotation and can be accessed with arrow keys or navigation buttons.
4

Delete Custom Backgrounds

Hover over a custom background preview and click the red trash icon to remove it.
Large images (> 5MB) may impact performance. Consider compressing images before uploading for the best experience.
Custom backgrounds are stored locally in your browser. They won’t sync across devices unless you use the same browser profile.

​
Background Navigation

  • Keyboard: ← and → arrow keys
  • Settings Panel: Click arrow buttons on either side of the preview
  • Preview: Shows current background with filename

Your language choice is saved and will be remembered for future sessions.
Language changes affect all UI text including tooltips, shortcuts, and setting labels. The musical elements remain the same.

​
Settings Persistence

All your settings are automatically saved: Stored in localStorage:
  • All volume levels
  • Auto DJ mode selection
  • Background ID and type (default or custom)
  • Language preference
Stored in IndexedDB:
  • Custom background images (full data)
Not Stored:
  • Current playback state (play/pause)
  • Currently active ambient tracks
  • Active environmental effects
This means your preferences persist between sessions, but the app always starts in a neutral state (nothing playing) when you launch it.
If you want to reset all settings to defaults, use your browser’s developer tools to clear localStorage and IndexedDB for the LoFi Engine domain.
