Legendary reverb engines

Equinox is built on the legendary reverb engines from Exponential Audio's Stratus and Symphony, bringing both hyper-realistic and creative reverb sounds into a single plugin. Place your instruments, dialogue, and more into a real space, or get creative and take them into new worlds.

Dynamic adaptive unmasking

Featuring easy-to-use dynamic unmasking, Equinox carves out space for your reverb, ensuring your mix is clean and focused. Keep dialogue present, vocals and lead instruments up front in your mix, and more.

Overhauled preset exploration

It's never been easier to find the perfect starting point for your reverb. Quickly and easily explore over 1250 presets from Stratus and Symphony with an all-new preset browsing experience, letting you search by multiple keywords and save your presets for later.

Refinable reverb character

The beauty of algorithmic reverb is that every aspect of your sound is yours to tweak. Dive into the advanced controls to sculpt the perfect space for any project and open the Balance tab to easily adjust and automate your reverb in surround audio formats.

Global tone control

Global tone control

Time is money, and sometimes you just need to make small adjustments and keep moving. Equinox's global tone control lets you apply a simple tilt EQ to your reverb signal, offering a quick way to make your reverb darker or brighter to match your needs.

Creative reverb effects

Whether you're working on a music mix or sound design for film/TV, Equinox has tons of features to make your reverb more unique.
