Audio professionals in search of a top-quality reverb will be impressed with the iZotope Exponential Audio Symphony, an algorithmic reverb that can add character and color to sound sources. This plug-in offers support up to 7.1 surround. As such, you'll find it suitable for both music and postproduction contexts.
Exponential Audio plug-ins trace their origin in the classic Lexicon units of yesteryear. This plug-in certainly expands upon that sound, adding color as well as dimension to your signals. This product is compatible with Mac and Windows platforms. It operates in AU, VST, and AAX formats. An iLok account is required for authorizing the plug-in, though an iLok key is not strictly necessary.
