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 factory IRs for a range of unique effects. And some reverbs, of course.
