Convolver is a plugin for doing realtime convolution using impulse responses from the user's hard drive. Convolution is the process of combining two signals to produce a third signal, which reflects their combined frequencies. For more information about the nature of convolution, check out the wikipedia entry on the subject, or for a more technical explanation, see the mathworld entry instead.

Convolution has a variety of uses, including filtering, room modelling, and amplifier modelling. The uses of this plugin are limited to whatever impulse responses you can provide it.

This plugin has a built-in file browser, gain adjustment, and can do high/low-pass filtering, which are applied to the impulse response directly before convolution.
