More than just reverb...

Convolution is a mathematical process through which one sound can be shaped by another.

Kilohearts Convolver is an effects plugin (VST/AU/AAX) that uses the mathematical process of convolution to shape the input using a prerecorded sound. You can record the reverberations in a particular space after a loud bang and use the resulting audio waveform (called an impulse response) to make your guitars, drums, synths etc. sound like they were recorded in that same space. You can also use impulse responses to convolve the effect of exotic filters, guitar cabinets, zany delays… pretty much any linear response effect you can imagine.

Convolver comes with 300+ carefully selected factory IRs, showing a wide range of the things it can do. But you can also load in your own samples and create convolutions unique to you.

To convolve is to multiply one sound with another… sort of.

The most common, and very cool, use for convolution is for reverb. If you go to a place with a nice ambience, like your local church or your grandmother’s bathroom, and you record the echo from a short loud click, you can convolve any other sound with the resulting impulse response (IR) and it will sound as if you were magically playing it in that location.

But that’s not all you can do with Convolver. Because IRs are simply audio files, you can load any sample into Convolver to emulate anything from a simple guitar amp cabinet to freaky filters, distinctive delays, and much more. To give you an idea, we’ve included over 300 factories IRs for a range of unique effects. And some reverbs, of course.
