Exponential Audio Symphony 3D
Surround and Immersive Algorithmic Reverb Plugin
Lush reverb for surround and immersive formats
Our 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.
The ultimate tool for lush, musical multichannel reverb
Symphony 3D is Exponential Audio’s flagship reverb offering.
The character reverb engine of Symphony receives 24-channel surround support, making it perfect for crafting distinct, captivating spatial effects for any multichannel music or post projects.
With independent parameter modules for the Attack, Early Reflections and Tail of your reverb signal, plus channel-specific Balance controls and creative modulation and dynamics effects, no other reverb plug-in gives you this much control over your multichannel reflections.
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.
When used in conjunction with Reverb Freeze, you can create nearly limitless original spatial effects for your music.
Expanded controls for creative precision
Tail Suppression and Recovery ensure that Symphony's reflections won’t overcrowd your mix or obscure any original audio.
Use the Balance module for channel-specific delay and level controls to decide when and where your audience hears the reverb in your mix.
