Reverb impulse responses

Free reverb impulse responses available for download for use in reverbs that can use them.  The impulse files available for download are 44.1 kHz, 32 bit, Wav format.

What are impulse responses?

When it comes to making music, impulse responses are used for convolution reverb, a process for digitally simulating the reverberation of a space. It is based on the mathematical convolution operation and uses a pre-recorded audio sample of a impulse response of the space being modelled. If we skip the mumbo jumbo it’s basically a way to sample a physical space or a reverb device so it can be used in a reverb. You can read more about convolution reverbs in the WikiPedia article or my explanation.

Reverbs that can use IRs

Fruity Convolver, SIR2, IR-1, Pristine Space, Altiverb, McDSP Revolver, Waves IR1 etc.

I spend a great amount of time on the AKRT projects and would like to continue the projects and similar future projects, if you want to make that easier for me please please consider to make a small donation.

Small rooms

A collection of Impulse responses recorded in small spaces. My most common use of these is to make synthesizers feel more alive but they work very well on drums and vocals too. These impulses have been edited quite a lot and I have used both real rooms and reverb units to create the impulses.

Speakers & amps

Impulse responses recorded from the cabinets of guitar amplifiers and speakers I like. These should be used with 100% wet on. That’s not a rule, but a tip.

AKIR Springer

These impulse responses will create a stable and clean spring reverb sound. I wanted a nice spring reverb sound but couldn’t find a plug (that didn’t use the iLok madness) so I tried to program one. The plugin is a great example of my mad skillz as a programmer as it takes about 98% of my CPU at a 200 milliseconds long buffer. In other words; useless if you want to use more than one plugin at a time or want to do anything were your DAW is even remotely responsive. The whole business was so unfulfilling until I made some impulse responses through it. The spring reverb could be sad to have 3 springs.

AKIR Smooth Springer

AKIR Smooth Springer is a smoother older brother to the AKIR Springer IR set. You could say it has it has six springs but ordered so it at sometimes sounds like 3 sometimes like 9. This creates a bit of a moving “chorusy” sound. A tad more unstable, bolder and cocky.

AKIR Uni Springer

AKIR Uni Springer is made using the same algorithm as the other ones. An emulated spring reverb. It sounds like butter.

AKIR Broken Springer

Something is a little weird with this one. Every spring starts to wobble a bit different.

Theres alot of weird things going on with this one but it can sound beautiful with synthesizers.
