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. To give you an idea, we've included over 300 factory IRs for a range of unique effects. And some reverbs, of course.
Start
Cuts the start off the impulse response. *
End
Cuts the end off the impulse response. *
Fade In
Fades in the start of the impulse response. *
Fade Out
Fades out the end of the impulse response. *
Stretch
Stretches the impulse response, adjusting both it's length and pitch. *
*Requires precomputation before the effect can be heard. Cannot be modulated.
Reverse
Reverse the impulse response before processing.
Select Sample
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.
Delay
Set the pre-delay time in milliseconds or as a fraction of song tempo.
Tone
Adjusts the brightness of processed output.
Feedback
Feeds the processed output back into the convolution engine.
Mix
The dry/wet mix of this effect. A lower value will let some of the unmodified signal through.
