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.
