Atmosphere Cloud Reverb For iOS

Blue Mangoo Software has introduced Atmosphere Cloud Reverb, a new Audio Unit effect plugin for iOS.

The company says that Atmosphere is “inspired by the Cloud Reverb patch in a very well-loved modern classic reverb pedal.”


  • Onset Time – Most reverbs have a pre-delay setting that delays the onset of early reverb a little bit so that the beginning of each note in the dry signal can be heard clearly before the reverb starts. Atmosphere Cloud Reverb does it differently: the reverb starts immediately with a low volume and fades in after the note attack with adjustable fade length called onset time, which replaces the pre-delay setting found on other reverbs. This doesn’t leave an unnatural empty space between the note attack and the onset of reverb, but it still keeps the early reverb volume low so that the note attacks can be heard clearly.
  • High Echo Density – Reverb effects typically take some time to build up echo density, meaning that the first few milliseconds of echoes sound a bit grainy. This reverb is designed with exceptionally high echo density right from the onset of the earliest reflections.
  • Stereo Modulation – Once you get beyond the early echoes, many reverb effects are simply a wash of evenly distributed, smooth sound. That isn’t necessarily bad, but when working with long decay times it’s much more interesting if there is movement in the late echoes. Atmosphere Cloud Reverb has two stages of LFO modulated pan effects and two stages of chorus modulation applied to the late reverb signal, giving it a big, wide stereo sound with gentle and complex side-to-side motion. The depth of these effects is adjustable using the mod control.
  • Long Decay Time – The longest echoes found in natural spaces last about 10 seconds. Long reverb like that can be observed in stone cathedrals. Similarly, reverb effects that are going for a natural type of sound often limit their decay time to a maximum of 10 seconds because artificial reverb can build up unpleasant resonances if allowed to ring too long. This plugin has a max decay time of 50 seconds, long enough for the most wet ambient music, and it maintains a beautiful, smooth sound throughout that entire time.

Pricing and Availability

Atmosphere Cloud Reverb is available now for $5.99.

  1. I really like Blue Mangoo’s products. Not a big fan of this reverb, in particular, but I guess I’ve got specific tastes.

  2. the ‘unnatural empty space between the note attack and the onset of reverb’ is actual natural acoustic behaviour – this is why everybody else has it. trying a different approach is nice, but saying it is more natural is not correct.

  3. Very nice reverb and I think they have a winner here, but I agree with mdesign here as well…certain synth patches work well with a more natural pre-delay. Also doesn’t seem to be a way to have modulation in the tail without having that panning effect present. For the synth patches that I like to use this type of reverb for, would be nice to be able to dial out the panning effect but leave the chorusing. Also a rate control for the panning/chorus would be really useful. Very good reverb overall….just needs a few minor tweaks here and there.
