Fog Convolver - Convolution Reverb and Processor Plugin (VST, AU, AAX) GUI


$ 42.25 $ 65


Fog Convolver is a true stereo convolution reverb/processor plugin. Convolution works by applying the sonic character of an impulse response to another sound in real time.
Fog Convolver can be used to add reverberation, create special effects, and apply an acoustic impulse captured from audio equipment.

An impulse response is a recording of the output that is caused by an acoustic space or electronic gear when an impulse is played (electric spark, starter pistol shot or the bursting of a balloon).

The factory bank features more than 250 impulse responses made from spaces, analog and digital equipment, speakers, organic sources, and more.

By clicking on the Mode box you can select two modes: Normal or True Stereo. True Stereo works by using two stereo impulse responses that are then mixed together.

You can either drag and drop two stereo files into the monitor (L+R) or you can drag separate stereo files (monitor top part for L, bottom for R).

True Stereo impulses are usually recorded simultaneously to capture a better stereo image, but you can also use two unrelated IRs to create experimental stereo reverbs.
