4Front Sand Brush completely regenerates high frequencies, basing on the existing partials. It can be used on hihats and other percussive sounds with high frequency content, and also on other tracks to add "sand".
Depending on the settings, it can also be used to emulate the vintage vinyl sound.
Primary design goals:
- Sand for vocal and solo tracks.
- Bring life back to sampled strings.
- Track restoration (including MP3).
- Vintage effect (to create vintage sound).
