I never came across a “simple as that” surround plugin. dearVR creates stunning 3D surround sound spaces and I love it! With it’s onboard “Virtual Acoustics” spaces, It has a fairly new approach for music production and I’ve heard some amazing examples for Audio book productions and ambient music. Some excellently tuned rooms for Drums, Vocals and other instruments create a new dimension for any type of Audio production. dearVR is a winner.
