DReverb

This free reverb can easily beat many paid ones. It can give you any sound you want - lush or grainy, clean or muddy, bright or warm. A huge spectrum for use. Well done Stone Voices.

The best free algo reverb available. This is the holy grail. Equal to Lexicon. The depth and image presented are rich and lifelike. No metallic or grainy tone. A reverb that sounds like reverberation rather than coloration. Full controls of all factors just like the best premium reverbs.

when i downloaded the plugin it had no parameter smoothing yet. i don't know if the developer has fixed that yet. that would be cool. apart from that it's just really good. has a great sound with a dark and smooth vibe to it, almost of wooden nature.

I also got the risk message but on another (freeware) platform you get the direct link and just can place the .dll file into your VST folder. No other files needed for installing.

To the plugin itself: I usually am no big fan of ambient reverbs, as they usually sound too digitally and synthetically to me, but this one really enables some nice, more naturally and organically sounding reverb tones, than I had expected, if properly adjusted. The possible long decay time is a nice additional feature for some self oscillation or drone sounds, although usually some seconds will be the sonically better solution.

Will not replace my (not so cheap commercial) favorite reverbs, but is a nice addition to them. Definitely worth a try.
