03In depth

Reverb engines and sound character

Equinox is built on the reverb engines from Exponential Audio's Stratus and Symphony. The developer describes it as bringing realistic and creative reverb sounds into a single plugin.

You can place instruments or dialogue into a real-sounding space, or move them into more unusual environments. Advanced controls let you adjust the character of each reverb, and a global tone control applies a tilt EQ to the reverb signal to make it darker or brighter.

Mix clarity, creative effects and workflow

Equinox uses dynamic adaptive unmasking, carried over from iZotope's Aurora and Cascadia, to carve out space for the reverb so vocals, dialogue and lead instruments stay forward in the mix.

Creative options include Freeze for sustained drones, plus Chorus and Gate. Tempo sync and tail suppression help the reverb sit in time with the music. The preset browser supports searching by multiple keywords and saving favorites.
