Bloom is a reverse reverb plugin for VST and AU formats, inspired by presets 41-49 on the Alesis Midiverb ii, a legendary multi-FX hardware unit originally released in 1987.
Bloom continually plays back a reversed copy of the audio that just happened 250ms - 750ms ago. You can control the reverse time and reverb response of the effect, making it tailorable to a variety of use-cases, from the subtle to the extreme.
