iConvolver is an app for conveniently utilizing convolution reverb on an iOS device.
Convolution is an effect that adds sampled reverberative properties to a sound to recreate the original properties of that sound. The data of these reverberative properties are called the Impulse Response(IR), and can record the properties of not only acoustic space but also from such things as hardware and speakers. By recording the properties of reverberation from acoustic spaces such as halls and studios, high grade hardware reverb, spring reverb, speaker cabinets and microphones, etc. to Impulse Response files, they can be reproduced in iConvolver.
As iConvolver comes with several Impulse Response files included, you can immediately test out those sounds.
