Envelope is a high class reverb audio unit for use as a standalone app, using Inter App Audio or as an Audio Unit in AUv3 hosts like Garageband, Cubasis or AuriaPro. Its true stereo reverberation algorithm creates ultra-realistic acoustic spaces. Eight basic room models are contained in this unit, all of which can be tweaked in size, predelay, depth, low- and high frequency content as well as stereo width. A dry-wet-control is also included, plus a carefully designed set of presets to get you started.
Envelope has already found its way into many recording studios around the world as a desktop plugin, and is now the first effect by the renowned plugin manufactory DDMF to be released for the iOS platform.

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!

Not a good reverb

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.

Fantastic Quality Reverb

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.
