PPT Echo and Reverb Methods - Montana State University buy, however, I want to simulate this effect digitally by using fast convolution techniques to replicate the delay effects of the Space Echo. In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more.This is accomplished by doing a convolution between the kernel and an image.Or more simply, when each pixel in the output image is a function of the nearby pixels (including itself) in the input image, the kernel is that function. The end product isn't to be a direct simulation of the Space Echo, but a new hybrid, which uses the impulse responses from the Space Echo to create a new plugin with my own features.
