Dragonfly Reverb "was released late in 2018 and quickly became one of the most recommended freeware reverb plugins. It is based on the
Freeverb 3 Hibiki algorithm which sounds simply amazing. The user interface is equally good, with easily accessible controls and direct access to all of the algorithm’s parameters."
