Verberate

The free Verberate Basic is based on Verberate 2 and offers the same highly praised audio quality. The plug-in offers four high quality presets from Verberate 2 that showcase the quality and versatility of the algorithm:

Plate, a realistic simulation of plate reverb with the typical frequency dispersion and decay properties that give plate reverb the airy touch
Room, a beautiful and warm wooden room that gives a great sense of room without being obtrusive
Hall, a natural and gorgeous sounding hall
Lush Hall, a colorful out-of-world hall with frequency modulated tails that sounds amazing on synth pads
The intuitive user interface has buttons for each of the four reverb programs along with a mix knob that let’s you adjust the dry and reverb signal levels.
