iZotope Symphony 3D: Crossgrade From Stratus or Symphony Standard

Sorry, this item is not available.

Reverb for surround and immersive formats.

iZotope and Exponentional Audio’s lush, colorful reverb engine gets a 24-channel upgrade in Symphony 3D, bringing rich modulation and dynamics effects to any surround music or post production. With channel-specific Balance controls and an expanded Warp section with Compression and Overdrive modules, Symphony 3D combines the creative power of R4 and R2 Surround while pushing their capabilities even further.

Stretch Time With Freeze

With the ability to create ambient textures and pads via the Freeze function, Symphony is not your average reverb plug-in. Freeze captures a moment of reverb in time and extends it indefinitely, making it a great tool for generating drones and textural effects.

Overdrive and Compression Modules via Warp

Symphony comes with Warp tools to bring out specific resonances in your music’s reflections and maximize the overall reverb signal. The Overdrive module gives you the ability to apply gentle harmonic excitement or full-on digital distortion to your reverb. When used in conjunction with the built-in Compression module, and even Freeze, you can create nearly limitless original spatial effects for your music.

Expanded Controls for Greater Creative Control

In addition to even more filtering controls, the Reverb Tail section features Tail Suppression and Recovery to ensure that Symphony’s reflections won’t overcrowd your mix or obscure any original audio. In Symphony 3D, independent Top Balance and Main Balance parameters provide channel-specific delay and level controls, so you decide when and where your audience hears the reverb in your mix.
