What Impresser does
The plugin is organized around three compression characters selected by ratio: at 1:1 it applies no gain reduction at all and works only as a harmonic enhancer, at 10:1 the Opto ratio delivers smooth, musical optical compression, and the Nuke ratio drives the signal into heavy pumping. The UK Mode, which the developer says recreates the character of the vintage All Buttons unit, pushes attack and release behavior into aggressive, explosive non-linearities.
Key features
- Ratio-selected compression modes. The 1:1 setting applies no gain reduction and acts as a harmonic enhancer, the 10:1 Opto ratio gives smooth optical-style compression, and the Nuke ratio squashes material into heavy, pumping grunge.
- UK Mode. UK Mode changes the attack and release behavior toward aggressive, non-linear response, modeled on the character of the vintage All Buttons unit.
- Side-chain filters. High-pass and band-pass filters in the side chain have adjustable frequency settings for shaping which part of the spectrum drives the compression.
- Mono and stereo operation. The plugin processes mono or stereo signals, following the layout used across Antelope Audio compressor models.
