Tired of the stock reverb in your DAW? Looking for a more modern sound? Zero Reverb is an Audio Unit Extension (AUv3) that works as a plug-in inside host apps. Just open up your favorite host that supports Audio Units and add it as an effect. The controls expand when touched so they can be easily seen while tweaking.

Zero Reverb will soon become your go-to reverb plug-in on iOS. Compatible with GarageBand, Cubasis, Auria, BeatMaker, AudioBus, AUM, Modstep, and more.

Zero Reverb is a high quality Feedback Delay Network reverberator. The algorithm has rich feedback with smooth decay for a modern hall-like reverb character. Blamsoft brings their experience creating high quality plug-ins for the desktop to iOS. The same algorithm is found in the popular Zero Hybrid Synthesizer Rack Extension for Propellerhead Reason. The available parameters allow you to dial in a wide variety of reverb textures.

Such A Classy Reverb

Blamsoft is paving a tough road to follow with their excellent suite of AU apps for iOS. This reverb is amazingly flexible for having such a stripped down interface. It invites you to just dive in and dial in the sound you need.

I've been using the "Abbey Road" approach to reverb recently, and using the dedicated low and mid times along with the cutoff filter, it is very easy to strip out the highs and lows and keep the reverb in the mids. But that's just one example. This is a class app capable of very nice reverbs for just about any occasion. And you can't beat the price! Highly recommended.

Still good.

Anyone who claims that this audio unit does not function properly in, GB, CB, Auria, BM3, Nano2 is not paying attention or something? IpadPro, iPhone 8. Good on all DAW’s. I like this reverb. It’s the 1st one I bought on iOS. I have everything in reverb land and it still has its own feel and sound. I like a lot.
Developers: More stuff iOS eventually? Please?

It works in garageband, people just cant figure it out

It works in garageband, people just cant figure it out. Go to plugins and eq under track controls, tab over to the correct file format and add the effect. clicking it once its added brings up the effect controls.
