IMPULSation is an impulse response/convolution reverb that allows you to load in your own impulses for an an unlimited amount of neverb and amp possibilities. To give you an idea of the power of this app: There are literally hundreds of thousands of impulses freely available online and our app will load them all, given that it’s properly formatted in either .wav or .aif format. Say for example you have an electric piano sound that you want to run through a classic Fender™ AMP. You do a web search for “Fender AMP Impulses” and pick from the thousands of possibilities. You will literally spend hours upon hours freely downloading all of the available spaces, amps, reverbs, and/or delays to use within your favorite AUv3 DAW.

The technology of convolving and deconvolving is a method of putting in a signal through an amp, reverb unit, delay unit, or space and with sophisticated mathematical interpolations techniques, you can create a very close replica of the actual source. Our IMPULSation is specifically designed for AMPs, reverbs, delays, and spaces of which our code is optimized to detect which is being used. The detection allows us to optimize the signal for better CPU and for optimal sound.

Import function broken in iOS12

Seems like importing IRs currently only work in iPadOS (iOS13), but not with older systems like iOS12.4. No IRs can be selected in the files app and all IRs are greyed out.

Looking forward to a fix and being able to rate this app higher, because this was the feature why i purchased this in the first place. It is conpletely useless as an IR loader at the moment. So don’t buy this app if that is what you are looking for and you are not running iOS13.

Developer Response ,

Please make sure to download version 2.0.1, where we fixed this issue and added some new features such as a Filter section.
