Reverb Character and Sound Design

Equinox combines hyper-realistic and creative reverb sounds in a single plugin. You can place instruments or dialogue into a realistic space, or move them into more surreal territory.

The advanced controls let you shape the reverb for each project, and the Balance tab handles adjustment and automation in surround audio formats. A global tilt EQ on the reverb signal makes it quick to darken or brighten the tail.

Creative functions such as Freeze for infinite drones, Chorus and Gate add unnatural textures. Tempo sync and tail suppression help the reverb sit musically in the mix.

Workflow and Compatibility for Existing Users

Equinox includes dynamic adaptive unmasking, which carves space for the reverb so vocals and lead instruments stay upfront and dialogue stays clear.

Stratus and Symphony users can import their own presets in one click. In Pro Tools, a backward compatibility workflow can replace each Stratus or Symphony instance in a project and match plugin settings to their Equinox counterparts.

Equinox runs in AAX, AU and VST3 formats on 64-bit systems. It is supported on macOS and Windows and works with hosts including Logic Pro, Pro Tools, Ableton Live, Cubase, Studio One and REAPER.
