Convolution... de-convoluted!

Convolution is, to me at least, a really inspirational subject. Why? Because it can initially seem like DSP magic, but it’s really not hard to understand at all. To understand the Fourier transforms for example, you first need to get to grips with imaginary numbers, Euler’s equation, rotation in the complex plane, and so on. This can make it a slightly daunting subject to learn. However, to study convolution you need little more than some high-shool level maths.

Simple Delay Effects (with iPlug Example)

A delay effect is often thought of as an “echoing” sound. However digital delay lines are also used to make other effects such as comb filters. The main concept that these effects rely on is feedback.
