Sometimes Mid/Side processing is called “sum and difference” or “sum and minus,” but we’ll stick with the standard Mid/Side name. Mid/Side processing, as the name suggests, allows the Middle and the Sides (L-R) of a stereo recording to be separated out from each other and manipulated independently. In this tutorial, we’ll learn about Mid/Side processing techniques, using the MASTER’s Mid/Side configuration as our example. The Muth legend continues in the Dangerous MASTER, a powerful and crystal clear mastering console complete with an all-analog Mid/Side Matrix, width control and insert loops.
Those innovations were a vastly important step forward for mixing and especially mastering. + AN INTRODUCTION TO LINE-LEVEL MID/SIDE PROCESSINGĭangerous Music’s chief circuit designer, Chris Muth, was the first person to design a device specifically for implementing Mid/Side processing for line-level audio signals, as well as the first to include insert loops for applying external signal processors like compressors and EQs.
