Reverb.com has released Reverb SOLO (developed by Acon Digital), a freeware reverb VST/AU/AAX plugin for 32-bit and 64-bit host applications on Windows and Mac OS.
Reverb SOLO was developed by Acon Digital, the company with a number of high-quality commercial VST plugins in their product arsenal, along with a fantastic freeware chorus effect called Multiply (it is listed as one of the top picks in our roundup of freeware chorus VST plugins). The company has also developed Acoustica Basic Edition which is listed as one of our favorite free audio editors.
I’ve always been a big fan of simple one-knob plugins (as long as they do the job well), so it’s no wonder that I find the idea of an easy to use one-knob reverb effect rather appealing. Of course, the fact that the plugin is easy to use wouldn’t mean anything if it sounded bad, but luckily Reverb SOLO is a very well made and pleasant sounding reverb effect.
So, how does it work? You get just a single knob, joined by a slider at the bottom of the user interface. The knob controls the size and tone of the reverb (from a tiny bright space to a larger, darker space), whereas the slider controls the mix. It’s not possible to alter the tone and size of the reverb in any way, apart from changing them simultaneously using the knob. The plugin also features a built-in preset manager (no factory presets), as well as undo/redo and A/B testing functionality.
Surprisingly or not, the reverb sounds very good and it works equally well for emulating small rooms and huge acoustic spaces. If you want to add some nice-sounding reverb to your mix as quickly as possible, Reverb SOLO seems to be the perfect tool for the task. After all, the included reverb algorithm is based on Acon Digital’s commercial Verberate plugin which is regarded as one of the best reverb effects on the market.
Before downloading your free copy of Reverb SOLO, you’ll be asked to registered for a free Reverb.com user account. After registering, you’ll receive a ZIP archive which contains separate installers for the 32-bit and 64-bit versions of the plugin (Windows only). There’s no need to activate the product after installing it.

Many thanks to @rekkerd for letting me know about the release via Twitter, cheers buddy!
UPDATE: Reverb SOLO is also available for Mac OS, in VST and AU plugin formats. Thanks for the comments everyone and sorry about the confusion!
