Für meinen Geschmack sehr gut ### 5/5 — Le Top. *2021-05-08, version 1.0.8* La meilleure reverb pour moi. Un son fantastique et musical qui pousse au maximum les capacités des sons notamment de synthétiseurs, mais pas que. ### 3/5 — Too Much Bugs *2019-03-13, version 1.0.6* It always crashes with GarageBand and the level effects is not accurate. For exemple you put 48% of reverb = not enough reverb, you put 50% = too much reverb. It’s a bit the same for the other effects. It could a very nice Audio Unit without the bugs !! ### 5/5 — Tops *2018-06-22* A very useful, warm/lush reverb. It has been among my go-to reverb effects for more than a year. ### 2/5 — Not a good reverb *2018-05-02* Okay, my standards are high because my primary reverb is a Strymon Blue Sky pedal and it’s absolutely astonishing, but this app is not studio quality reverb. It colors the sound, deadening the harmonics and overtones, which is what you’re usually trying to bring out with a little reverb. The wet/dry mix knob is practically an on/off knob at about 70% mark. The predelay doesn’t blend well, instead abruptly introducing the reverb sound at whichever ms delay you’ve chosen. But worst of all it’s just tinny and metallic sounding. It’s hard in the ears. ### 5/5 — Incredible! *2017-12-09* An unbelievably good enveloper. The presets are as good as you’ll get on iOS 11. I have the plugin version of this too for Logic Pro X, and it’s equally as good. One small request would be to add an iPhone X update. A “Must Own” app! ### 1/5 — Not much use *2017-07-01* The sounds generated can be immense, but the process of getting there is hazardous. Twiddly knobs and with each turn of the dials there's Crackle and stutter i.e. heavy static. Other than the App Store one could request a refund. Well over priced ### 5/5 — Fantastic Quality Reverb *2017-03-04* Works in Auria for me...absolutely incredible reverb and gorgeous to look at! High Quality plugin app but does require a lot of CPU. Would be perfect with iPad Pro. ### 5/5 — This reverb is in the same class as $1000+ classic hardware units *2017-01-05* DDMF has made a name for itself in the desktop DAW plugin space and now they bring the exact same power to iOS. If you own & use Auria Pro and have spent the additional dough on any of the FabFilter plugins you know what professional quality effect plugins can do in iOS & iPads. This reverb (and the equally impressive Neve style EQ) are must buys. ## Frequently asked questions about Envelope AU Reverb by DDMF ### What is Envelope AU Reverb?
