Convolver

Convolver is designed to do realtime convolution using impulse responses. It 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.

Realtime convolution is the process of mapping a signal to reflect the frequencies of an impulse response (IR), also sometimes referred to as an "impulse curve". An IR is basically the set of frequencies that define how sound reacts in a certain environment, and the process of mapping these two frequencies together is convolution. The convolution algorithm is very useful for many common audio-processing tasks, such as room-modelling and filtering.

Convolver offers users the ability to use IR's from their hard drive - unlike other convolution plugins it does not have built-in IR's, nor does it use a proprietary IR format. It can load the following types of files: WAV, AIFF, AU, RAW, PAF, IFF/SVX, SF, VOC, W64, MAT4/MAT5, PVF, XI, HTK and CAF.
