More than just reverb...

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 your 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. Then process them with a much wider array of controls than you'll find in other convolution plugins. To give you ideas, it includes over 300 factory IRs for a range of unique effects. And some reverbs, of course.

Convolver comes with a large library of Impulse Responses that should cover many of your basic needs. But you can import any samples you want.



Set the pre-delay time in milliseconds or as a fraction of song tempo.

Feeds the processed output back into the convolution engine.



The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.

They are lightweight and powerful plugins that present you with the important settings in a no-nonsense way, so you will be using them like a master in no time.
