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.

Nice lush reverb

Big upgrade from most of the native plug ins for Cubasis and Auria. Simple clean interface ,really adds depth while still sounding natural. AU is very efficient and is not a CPU hog. Huge props for being one of the first with quality AU implementation.

Want my money back. It simply does not open. Opens the instructions instead.

Developer Response ,

Opening the app does indeed show the manual. But the app installs an AUv3 plugin that is available in host DAW apps. If you are not familiar with AUv3, I suggest starting with GarageBand. You can add the plugin as an effect to a GarageBand instrument track. In GarageBand, tap "Plug-ins & EQ". Then tap "Edit". Tap a green plus sign button to add an effect in an empty slot. Then you will see "Audio Unit Extensions". Choose Zero Reverb from the list.
