Fabfilter Pro-R - High Quality Algorithmic Reverb The Fabfilter Pro-R is a pro reverb plug-in that sounds natural and sits in the mix perfectly. At the same time, it should not confuse you with over-technical controls, but must be easy to set up and a joy to work with. Enter FabFilter Pro-R. FabFilter Pro-R takes a musical approach to reverb, offering user-friendly, non-technical controls like Brightness, Character and Distance to achieve the reverb sound you are looking for — without requiring a degree in reverb science. The stepless Space control lets you fade between dozens of different, carefully tuned room models, automatically choosing a matching decay time for a natural-sounding result. The decay time of a real room often varies wildly over the frequency spectrum, which is one of the key ingredients of a room's reverb character. To simulate this, the industry-first Decay Rate EQ concept in FabFilter Pro-R offers completely free adjustment of the decay time over the frequency spectrum.
